LP1970476 Where filter in Bootstrap Catalog Produces Unwanted Results

Prior to this change, the Advanced Search page split the library selector
and the "Where" scope selector into two separate dropdown lists that
produced unexpected results when both were used.

This change uses the same approach as the combined dropdown on the Basic
search page instead.
