Bugfix/nested elements and revisions

[i-just]

Description

Issue 1:
When viewing a revision of an entry with a matrix field in cards or element index mode, double-click on the nested entry to open a slideout. Notice that the buttons at the bottom of the slideout say “Cancel” and “Save”. Clicking the “Save” button triggers an error.

Solution:
When viewing a nested entry that belongs to a revision, don’t show the “Save” button and change the wording of the “Cancel” button to “Close”.

Issue 2:
When viewing a revision of an entry with a matrix field in cards or element index mode, double-click on the nested entry to open a slideout, then click the external icon to open the nested entry in a new tab. Notice that the “Revert content from this revision” button shows.

Solution:
Hide the “Revert content from this revision” when viewing an element that doesn’t support revisions (on its own).

After:

Issue 3:
Create an entry (that has revisions turned on) with a matrix field in cards or element index mode, and add a few nested entries to the matrix field, save. Remove one of the nested entries and save. View the revision that should still have the deleted nested entry - it still shows, but if you try to open it by double-clicking, you’ll get an invalid owner ID error.

Solution:
When getting the element in the ElementsController, if we have a revisionId, ensure we include trashed elements too.
