Ed Sanders d8d3a8c98e Defer building of MWReferenceSearchWidget index
It can be very slow on pages with lots of references and
isn't required until you click 'Use existing reference'.

What is required is knowing if the list will be empty for
greying out the button, but that can be precomputed very cheaply.
