    libtracker-data: Handle tracker:fulltextIndexed changes
    
    We no longer have a reason to deem this change incompatible. Since
    no actual text is stored in the FTS tables, and it merely updates
    its tokenization info from the original class tables, we can just
    drop this info and reconstruct at will. So there's no longer need
    to consider tracker:fulltextIndexed changes as incompatible.
