Translation update: Fix after recent changes to Blender init code.

Recent changes broke calling an operator from python too early during
init process, including during first draw calls.

So now moved most of `UI_OT_i18n_updatetranslation_svn_init_settings`
logic into a static method that can be called directly in this specific
case.

Also improved situation where init fails, by showing the reset/init
settings operator in the UI still.
