[tracker/wip/carlosg/backports-3.3: 2/7] libtracker-sparql: Do not attempt to rebuild non-existing FTS tables

[Carlos Garnacho <carlosg src gnome org>]

commit e6476933138f6a07022a2e95c9f3b9ba0c25be1d

    libtracker-sparql: Do not attempt to rebuild non-existing FTS tables
    
    If a database/ontology has no fulltext-indexed properties, we do not
    create a corresponding FTS table. Likewise, parser/locale updates
    should not attempt to update it, or we will get a "SQL logic error"
    poking non-existing tables.
    
    Closes: https://gitlab.gnome.org/GNOME/nautilus/-/issues/2278
