Xqt made gerrit:178796 <https://gerrit.wikimedia.org/r/178796/> not
depend on gerrit:179591 <https://gerrit.wikimedia.org/r/179591/> anymore.
The latter should be merged, or the former should be reverted, because
of failing tests
<https://travis-ci.org/wikimedia/pywikibot-core/jobs/44055432>.
I remember this already happened some time ago. Please do not remove
dependencies from Gerrit changes without accurate checks.
