Make the product filter in invoicing work again

If creating an invoice you can not longer remove filters that are in use on the products page. without closing the invoice page opening products page removing the filter and then open invoice page and start again.

This used to work in version 28 and has been disabled in V29 although the remove filter button is still there it does not work.

I suggest testing before releasing 'upgrades' might be a good idea

Sage should be a business tool which facilitates the operation of a business, rather being a program for people to use and call that work.
