CSPACE-3077, 2742 - Get rid of test/test accounts, and super-admin role. Removed sql-script based initialization of test accounts, users, and roles. Changed default credentials used in XmlReplay tests to use tenant admin account. Changed ServiceMain to create SPRING_ADMIN_ROLE, rather than set it up in the sql scripts. Removed and updated a number of account and authentication tests that were in error, and depended upon the test accounts initialized in sql scripts.
