[FIX] website,website_sale: Dynamic products isn't visible if category deleted

Issue

	- Install "Ecommerce" app
	- Go to 'Shop' page and edit it
	- Add a "Dynamic Products" block
	- Click on it to edit it :
	-  Select any template
	-  Select `Desks` as product category
	-  Save
	- Go to "Website -> Configuration -> eCommerce Categories"
	- Delete the "Desks" category
	- Go back to Shop page

	Error : "Record does not exist or has been deleted".

Cause

	The search domain is looking for child categories of dataset.productCategoryId
	(who does not exist anymore in the above case).
	`child_of` do a browse() to fetch the records, and therefore generate
	an error if category not found.

Solution

	Check if dataset.productCategoryId exist before updating domain.
