(Bug 49490) Prefix ref name/group before using as property key

* The page in question "es:Estadio_Deportivo_Cali" had a ref
  with name "constructor", and this name was used as an object
  property key and this clashed with the predefined property
  constructor.

* The reliable solution here is to prefix ref-name and ref-group
  with a string and use it to prevent clashes.
