Locale Kit: move catalog add-ons loading to early initialization

Browse Source 
The catalog loading has been done lazily since forever (this code was
imported from OpenTracker). It results in a race condition as explained
in #16670.

Moving the catalog loading earlier in the locale loading process avoids
this problem, since load_add_on is called before the locale roster lock
is used.

This should fix #16670.
