The !162 (merged) caused that language chooser have all lines selected if cc_language_chooser_set_language() is not called before use.

This happens in Users panel for users without language set (just for first time):

1. Create new user, or choose some without language set
2. Click to language button

I can fix it in Users panels by the following, but I think that it should be fixed in language chooser directly.
