cli: make squash and unsquash commands record abandoned commits

Browse source 
This change makes `jj squash` and `jj unsquash` record the child or
parent (respectively) as abandoned if it becomes empty. We need to do
that because it won't get automatically recorded by
`CommitBuilder`. We could make `CommitBuilder` record abandoned
commits when `set_pruned()` was called, but that would be
short-sighted since we're about to delete that function as part of
removing support for evolution (#32).
