When using statement based replication in a master-master configuration

Browse source 
there exists a race condition that can break replication when dropping a user.
Ideally one would use the "sql_log_bin: no" option to avoid this but
that is not possible on Google CloudSQL instances. Adding IF EXISTS
clause to the DROP USER statement makes it replication safe without
the need to skip logging.
