BUG#6749: If there is no current database, then nothing should be binlogged if

binlog-do-db or binlog-ignore-db are in effect.   (In the future 5.1? 5.0? I think 
each statement should be verified against the filtering criteria based on the database
it *uses* and not the *current* one.  But, right now the *current* database is what 
counts according to the semantics of the manual.)
