mq: use ui.allowemptycommit to allow empty commits

Previously, mq used the force flag to allow empty commits. Now that we have
ui.allowemptycommit let's switch to that instead. We can't completely remove the
force flag since it is used for a bunch of other behavior in localrepo.commit.

  $ hg init 1

  adding foo
