[PRF] sale*: avoid useless recomputations

By default, a related field dependencies are the fields in his relation 
path.
But for non stored UX fields, the field should only be recomputed when
values editable in the view are edited.

Example:

On a given model:

product_id = fields.Many2one(...)
product_type = fields.Char(related='product_id.type')

The product_id field can be changed on the model view, but not the 
linked product,
so there is no need for the orm to search records whose product_type 
must be invalidated
when the type is changed on a product.

To avoid this 'useless' search, we can manually restrict the field 
dependencies:

product_type = fields.Char(related='product_id.type', 
depends=['product_id'])
