Fix for small bug #186 (If a connection has temporary tables and does

Browse Source 
RESET MASTER, this breaks replication).
In the slave SQL thread, any DROP TEMPORARY TABLE is silently
converted to DROP TEMPORARY TABLE IF EXISTS, not to have irrelevant
"table does not exist". See comments in code or bug #186 for an example
of how irrelevant errors like this can arise.
