Issue 108: Verifying a new user account does not unlock that account

[ddelponte]

• added a test to verify the verify registration functionality is working as expected
• modified the SpringSecurityUiService.save to flush on save.  I've verified this fixes the failing test that was reported.

This is a fix for Issue https://github.com/grails-plugins/grails-spring-security-ui/issues/108
