[FIXED JENKINS-22570] On a configure screen that has multiple groups …

…of radio buttons, clicking the apply button clears all but the last radio group selection

- Changed from mutating the e.name value to maintaining an index and using that index to get the required substring

- Risk of unintended consequences is low. The Submit flow moves off the page before the consequences of the effect
  could be seen... though a careful attention to the page submit can identify the change... and the page is now
  left as before clicking f:apply instead of mutated.
