Bug 36334: Remove unnecessary JS code from member.tt

Bug 36334: Remove unnecessary JS code from member.tt

This was initially written to set the input/select in the form in the
left side of the main patron search page.

But this is now done in patron-search.inc:
koha-tmpl/intranet-tmpl/prog/en/includes/patron-search.inc:
  <input type="text" class="search_patron_filter" value="[% search_filter | html %]" class="focus" />

I don't see how/when this code is still used.

Additionally:
 #searchmember_filter
 => does not exist, it's .search_patron_filter

 $("searchfieldstype_filter").val("[% searchfieldstype | html %]");
 => Not a valid selector
