bugfix for crosswalk not maintaining licence aspects for non-cc licences

@emanuil-tolev - fixes bug with the crosswalk which does not keep the BY/NA/SA/ND aspects of non cc licences on form save.

This is my first proper gitflow hotfix, and I created it from the develop branch, which I realise was probably wrong.  Nonetheless, it should apply comfortably to the master branch, and as you can see only affects a few lines.
