Merge ext.uls.eventlogger into ext.uls.common

This could've been done longer ago (by defining ext.uls.common
in Hooks.php), but didn't notice it before.

The ext.uls.eventlogger was (if configured) loaded on all page
loads. Same as ext.uls.init (but without config condition).

ext.uls.ext is an empty shim around ext.uls.common, which is thus
also loaded on all pages. Merge this into there given has no
reason for being its own module. They are always loaded together.
