mq: look for modified subrepos when checking for local changes

It was possible to apply, unapply, fold, patches (etc) with modified subrepos,
which resulted in surprising behavior. For example it was easy to apply a patch
with a modified subrepo, and then the refresh it and accidentally end up
including the modified subrepo on the refreshed patch.

A test has been added to verify this new check.

Try both orders.
