summary: Check that snap disconnect works
details: |
This test verifies multiple ways to invoke "snap disconnect". It
can disconnect specific connections, or all connections to a plug,
or a slot. Forgetting connection should be correctly saved. Both
connections to snapd and other snaps can be disconnected.
