summary: Test remodel
details: |
Check that when `snap remodel` is executed, then it uses the new model
assertion and the required snaps defined in the new model are installed.
Verify that the required snaps cannot be removed, but after remodel
back to the initial model, the required snaps are not still required
and can be removed.
