Since the usage of the `CSS Grid` some view are broken due to too much
CSS rules conflicting together.
The new form view system is less tolerant to missing colspan.
This commit, change the colspan when needed (e.g. no label)
Steps to reproduce:
* Go to sale
* Select the product menu
* Select a product (e.g. Printer)
* Some fields on the form view (in panel) are not aligned => BUG
