[BZ 1122549] - LDAP user registration screen does not appear when 'Enable Login Without Roles' has value 'No' - SubjectManagerBean.processSubjectForLdap() was calling the SubjectManagerBean.login() where the exception was thrown, but the roles get assigned after this step. Now the login method is called with additional parameter that says 'don't do the role checking'. There was also a logical error that actually caused that no RHQ roles (based on LDAP group) were assigned at all (it was done correctly only when the log level was set to DEBUG)
