Make all queries/updates in tracker-miner-fs compiled statements from a gresource.

Move towards tracker_sparql_connection_load_statement_from_gresource() and query/update statements for all queries done in the tracker-miner-fs-3 process. For this, the TrackerSparqlBuffer object has turned into a "change log" of sorts, where all file modification updates (move/delete/update/...) are pushed into, in order to keep all related statements nearby.

Depends on tracker!576 (merged)
