    libtracker-data: Allow calling tracker_db_manager_locale_changed() before init
    
    This fixes an issue introduced in commit fa6317fbabb1a7, where the
    direct backend would fail to find the 'db-locale.txt' marker due to the
    global 'data_dir' path variable being NULL at the time it called
    tracker_db_manager_locale_changed(). It would then report that the
    locale had changed from 'unknown' to the system locale, and abort.
