[FIX] pos_self_order: condition opening product window

Nothing will happen if you click on a product without image, sale comment
and attributes in selfOder if no table was selected before.

To reproduce the issue:
1. Create a product without image, sale comment and attributes (Fill in product name, price, availible in pos)
2. Open a new selfOrder page (without a table selected)
3. Click on the product

Issue: nothing happens, the product cannot be ordered. If no product meets
at least one of the three conditions (image, sale comment or attributes),
it will not be possible to select the table, and thus self-ordering will
be impossible. In fact the table selection only happens during the first
order.
