Description of problem:
Using Errata Installation for a Host Collection has multiple issues, all related to incorrect handling of errata selection .

Version-Release number of selected component (if applicable):
Sat 6.6 Snap 11

How reproducible:
always

Steps to Reproduce:
1. Create a Host Collection and assing multiple hosts with installable errata to it. I have used released RHEL 7.6 without any updates.
2. Navigate to Hosts-> Host Collectins -> <host collection created in step 1>
3. Click Errata Installation

Now you can encounter multiple issues with a common root cause (I guess):
You start with pagination of 20 items per page by default. Select a few errata (3 in my case).

- if you change the page, you can see there are still 3 of 80 errata selected. If you change the page back to the initial one, there are still 3 of 80 selected, but you can't see the checkmarks at the errata you have previously selected anymore - all checkmarks are empty.

- same thing happens if you change the pagination number e.g. from 20 to 50. Checkmarks are gone, yet the dialog still states there are 3 of 80 selected.

- only way how to clean the selection is to click on the "Refresh Table" button, close the dialog, or click the "select all" checkmark button in the column header.

- if you use the column checkmark button to select all errata, only the errata on the current page is selected. Fair enough. The problem is, if you switch the page, naturally no errata is selected on the the new page, but the column header check button is still checked. Clicking it clears out the selection you have made on the previous page, and has no effect on the current page selection. It means the user is not able to select all the errata on a multipage dialog using the column button - only by manually clicking each erratum on subsequent pages.

- this works the other way as well - if you manually select some errata on one page, then switch the page, and use the check button in the column header to select all errata on the current page, previously manually selected errata is cleared, and only the errata on the current page is selected (at least according to "x of y selected" line, as it is not possible to check the selection because of the issues described above)

- if you successfully select all the errata on all pages in the dialog, change the page again, and then manually start selecting the (now clean) checkmarks, the status line starts to overflow, showing things like 90 of 80 selected. See the attached screenshot.

- as for the functionality itself - changing the page really clears the selection, even if the status line claims there are some errata selected. The "Install Selected" button is still active and can be pressed. Doing so causes the an error message "No content has been provided". Only checkmarks that are actually present and visible are taken into account when submitting the installation job.

Actual results:
The checkmarks handling is inconsistent, and it is actually not possible to select errata from multiple pages.

Expected results:
Checkmarks are preserved despite the page and pagination size changes. The status line showing number of selected errata reflects the real state of selection. Errata on multiple pages can be selected.
