Disabled "Collapse" button in "Flat" view (#1855)

Our `DiffResultDialog` and `ExtractDialog` show a context menu for items of the list/tree view. The collapse action in this menu only makes sense for the tree mode of the view. This commit therefore enables the option only for this view mode.

* src/vorta/views/diff_result.py

* tests/unit/test_diff.py : Add tests for the new behaviour.
