Bug 22419: Records listed twice when select/unselect all from the cart

It fixes a browser timeout when records are removed from the cart.
The onchange event already call selRecord.

Test plan:
Launch a search
Add all the result to your cart
Open the cart
Click "select all"
Then remove them all from your cart
=> Without this patch the action will timeout
=> With this patch applied the action is immediate
