rebase: in --confirm option just abort if hit a conflict

Before this patch, it was prompting the user in both cases 1) when
there is no conflict 2) when there is at least one conflict. But
for simplicity we can just abort if we hit a conflict and no need to
prompt in that case.

# extension to emulate invoking 'dirstate.write()' at the time
# specified by '[fakedirstatewritetime] fakenow', only when
# 'dirstate.write()' is invoked via functions below:
#
#   - 'workingctx._poststatusfixup()' (= 'repo.status()')
#   - 'committablectx.markcommitted()'
