revlog: adapt the `reading` check for `unionrepo`
We cannot just rely on the length check for the `unionrepo` as the local revlog
might be empty while the other revlog contains data. In addition, we need to

creating 'remote' repo
$ hg init remote
$ cd remote
$ hg unbundle "$TESTDIR/bundles/remote.hg"
