    libtracker-data: Trigger rebuild of FTS tokens on parser changes
    
    Whenever there's a change in the implementation of our tokenizers, we'll
    trigger a rebuild of the FTS table. This allows for live updates to our
    tokenizers without the need to redo the database from scratch.
    
    The FTS rebuild is also triggered on locale changes.
