In https://bugs.eclipse.org/bugs/show_bug.cgi?id=573086 the representation validation was moved from an adapter to a post-commit listener and it fixed the issue in Capella because there is a specific label provider that refreshes the representation label in the model explorer view. However, for Sirius this is not enough and should be fixed. Note that even if in the explorer it looks as invalid, it can be opened and renamed correctly. It is just a visual issue.

Step to reproduce:
- Open a modeling project
- Open the aird editor
- Remove an existing representation
- Undo
-> The representation should not appear in gray
