mq: pop/refresh: avoid losing revisions not managed by mq

We already disallow committing on top of an mq revision exactly
to avoid losing this new revision during a qpop/qrefresh, so this
can be seen as an additional safety check.

If this is not enough to fix issue844, it should at least prevent
it from happening.
