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.

The modules 'ext.uls.init'/'ext.uls.common' provides only a library and
no own funtionality. The modules get automatically loaded through
dependencies by other modules when needed as library. An explicit
loading on all page is not necessary. For example the MediaWiki API
help page does not have any ULS elements.

Given the code no longer uses any EventLogging methods directly,
but rather mw.track(), this means it also doesn't need to declare
any dependencies, including for older MediaWiki versions this
will work as-is.
