    libtracker-data: Transfer parameter types correctly to SERVICE patterns
    
    It's better not to rely on internal casts to/from strings working (may
    be troublesome with e.g. rounding with certain doubles). Transfer the
    types obtained to the internal statement, so those reach the external
    service.
