Test rpl.rpl_rotate_purge_deadlock has incorrect preamble

Test rpl.rpl_rotate_purge_deadlock has in the beginning:

source include/master-slave.inc;

source include/have_debug_sync.inc;

source include/have_binlog_format_row.inc;

source include/have_innodb.inc;

It means that when debug_sync is not enabled, or binlog format is not 'row', or there's no innodb master-slave configuration will be already set up and won't be torn down. So any subsequent test involving master-slave configuration will break because it won't be able to set it up.
I guess just making master-slave.inc the last in this list is enough to fix the problem.
