Docker Tag page missing manifest type
DockerTag details page used to show details like "Manifest Type" as image/list ( https://user-images.githubusercontent.com/1069779/32075294-5bba5720-ba6a-11e7-9e8c-0855b38fa5d9.png)
My guess is its related to changes in https://github.com/Katello/katello/commit/1fc82810ba25036abae9d7d2ce0caf5eb3b81956
2 errors that need to be fixed on this page
1) Show manifest type
2) Don't show schema information if tag does not have a schema version. For some reason ""!_.isEmpty(tag.manifest_schema2)"" is not failing if manifest_schema2 = null. I am again guessing its related to changes in the above commit.
Fixes #21692 - DockerTag Info shows Manifest Type
Commit 1fc82810ba25036abae9d7d2ce0caf5eb3b81956 introduced a minor error
in the DockerTag info screen. The Manifest Type (List/Image) were not
getting displayed and the logic that said 'do not show schema version
information if its not present' wasn't getting handled correctly. This
commit fixes that issue.
