rdf_reset_db

Remove all triples from the RDF database and reset all its statistics.

bug: This predicate checks for active queries, but this check is not properly synchronized and therefore the use of this predicate is unsafe in multi-threaded contexts. It is mainly used to run functionality tests that need to start with an empty database.
