summary: Check snap remove operations.
details: |
Removing a snap is somewhat non-trivial: services need to be stopped, all
the revisions need to be unmounted, a snapshot of data is taken for
preservation, the snap file itself is removed. For snap packages that are
bases there cannot be any snap applications that rely on the base to be
present.
The test checks a small subset of that set, namely that removal affects all
revisions and that a base snap is not removable for as long as there are
other snaps referencing it.
