MWReferenceSearchWidget buildIndex optimisations

Browse source 
* Each item builds an MWReferenceModel which creates a document
  slice clone. This is very expensive and we only use the model
  for getting basic attributes, so defer the evaluation of the
  document.
* $.show is expensive and, in this case, unnecessary.
