WB2: after trashing a collection, the collection context menu (three dots, upper right) is not refreshed, which means that it still has the "Move to trash" menu item, rather than "Restore".

TODO: change this UX: when a collection is trashed, redirect the user to the project that it was in. When deleting a project, we also want this behavior (worst case, we redirect to the home project).

Rationale: when a user trashes something, they want it to go away. This also solves this bug.
