Remove default usage of --ask

--ask is no longer used when installing AUR packages, instead pass no
confirm when we know there are no conflicts and wait for manual
confirmation when there are.

This means that when there are no conflicts there should be no change in
behaviour and the user will not need to intervene at all.

The old behaviour can still be used with --useask.
