JIRA test checks for UUID when connecting to Crowd

After configuring Crowd and running the test, it seems to do a test for the Unique User ID attribute. This attribute is not actually needed for JIRA+Crowd integration, it is only used for LDAP. This could cause confusion for customers who setup JIRA + Crowd.

This does not actually affect the integration between JIRA and Crowd. The users are properly sync'd and renaming users works fine.
