Bug 11273: FIX barcode generation in acquisition if hbyymmincr

When AutoBarcode is activated and you have set AcqCreateItem to 'on
order' there is a Javascript error when you try to generate a barcode
for the item:

TypeError: document.f is undefined
http://localhost:8080/intranet-tmpl/lib/jquery/jquery.js
Line 11

Test plan:
0/ a. Set AutoBarcode to hbyymmincr
   b. Set AcqCreateItem to 'on ordering'
   c. Set the plugin barcode.pl to the barcode field for the default
   and the ACQ frameworks
1/ Go on the add items page (cataloguing/additem.pl) and confirm that
the plugin works as expected.
2/ Go on the New order page (acqui/neworderempty.pl) and confirm that
the plugin works as expected.

Followed test plan, works as expected.
