Uncaught TypeError: Cannot read property 'prototype' of undefined

@p4st0r still having this issue? Please respond within 7 days or this will be presumed as no longer an issue :)

Can confirm this issue on all FreeFlarum forums. Disabling reflar/nightmode recovers the error.

Possibly related:

Running PHP 7.2.19-0ubuntu0.18.04.2, MariaDB 1:10.1.41-0ubuntu0.18.04.1 and Firefox 68.0.2+build1-0ubuntu

This can be fixed with an initializer priority. We also probably want to make sure flarum/tags is loaded & enabled before extending anything.

@gwillem @p4st0r we're going to attempt to fix this issue before we release this into the FoF namespace.

@datitisev suggests wrapping that TagsPage extender with if (TagsPage) but we'll see what that does 👍
