1) team-ross.api.php: Fixed foreign key referential integrity error
	a) added SET foreign_key_checks=0,1 before and after INSERT statement to
	   substitute for use of DEFERRABLE (MySQL doesn't support DEFERRABLE)
See: http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html

2) test-harness.php: Added ON UPDATE CASCADE for LocationOffersCatalog create table statement.
