Fix for BUG#4551 "Temporary InnoDB tables not replicated properly with CREATE TABLE .. SELECT"

Browse source 
The problem was that (for any storage engine), the created temporary table was not removed if CREATE SELECT failed (because
of a constraint violation for example). This was not consistent with the manual and with CREATE SELECT (no TEMPORARY).

# Testcase for BUG#4551
# The bug was that when the table was TEMPORARY, it was not deleted if
# the CREATE SELECT failed (the code intended too, but it actually
# didn't). And as the CREATE TEMPORARY TABLE was not written to the
# binlog if it was a transactional table, it resulted in an
# inconsistency between binlog and the internal list of temp tables.
