summary: Simple snap prefer test
details: |
Snapd allows selection of preferred source of aliases for snap applications.
The "snap prefer" command can override manually created aliases as well as
default aliases of other snaps.
The test installs a snap with automatically enabled aliases, uses the "snap
unalias" command to remove them, then uses "snap prefer" to re-install
automatic aliases and ensures the expected aliases are re-instated.
