Importing a new manifest does not remove old manifest entitlements from Subscriptions; error/spinner thrown on view
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1207501
Description of problem:
When importing a new manifest (after deleting old of course), the numbers for the old manifest still show up in Content > Red Hat Subscriptions. Clicking the link for that those entitlements sends up a perma-spinner, with a big trace in logs.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Import a small manifest with 10 entitlements; consume some of these
2. Delete that manifest and import a larger one with 50 entitlements.
3. Go to Content > Red Hat subscriptions
4. Click the link for the old (consumed) entitlements.
Big log trace (forthcoming)
Traces of old subscription wiped out.
Notably, when I move my systems over to the new inventory (i.e., it should read 4 of 50), nothing ever gets updated there, either. Not sure if this is part of the same issue.
