LP#1406387 Fix for Holds Placement Advanced Options

LP#1406387 Fix for Holds Placement Advanced Options

In the staff client, when placing a hold and clicking
Advanced Hold Options, the barcode input will populate
with the staff member's barcode if it was previously
empty, regardless of whether the radio input for the
hold was specified for a patron or the staff member.

This patch corrects that behavior, and also populates
the input radio on load after clicking Advanced Hold
Options.
