Fixes Check-All and Uncheck-All Features Not Functioning in "Multiple Target" Language Selection on Sources Page

Drupal Added js- to one of the selectors causing the check functionality not to work, The addition to that the code triggers multiple times due to the utility function once is missing.

Ah, I guess claro renamed the form item classes (and so does gin I assume). Using the js prefixed classes makes sense, that's what they are for. Should we maybe also remove some of the extra classes like details-wrapper? I doubt that adds anything meaningful here, the tmgmt-source-checkout-wrapper should make this specific enough?

yes, you are absolutely correct. We don't need this class, even on the targetLanguagesCheckboxesWrapper.
