Have the test suite check error messages. Since XMLRPC doesn't give us structured error information, just compare the resulting text. Fix messages that tests expect to cause. Minor changes: Make netgroup-mod's NotFound message consistent with other objects and methods. In test_automember_plugin, test with nonexistent automember rules of both types, instead of nonexistent users. https://fedorahosted.org/freeipa/ticket/2549
