Bug 10786: fix Javascript error on the parcel page

The include of the yui json file generates a js error: YAHOO is not
defined.

This file seems not to be in use (patches for bug 8382 remove the use).

To test:
- go on acqui/parcel.pl?invoiceid=XXX
- verify the error occurs (with firebug)
- apply this patch
- refresh the page
- verify this error does not appear anymore
- Verify there is no regression on this page
