[FIX] POS: search from database doens't rewrite available_in_pos

Observed Behaviour

When loading limited number of products in POS, we have the "database search"
functionnality allowing use to search in non-loaded product. Anyway, using this
method will make all products found in the search available in POS, despite
having set it to "False" on the product page.

Desired Behaviour

This search method should only search on the already checked "available in POS"
products and shouldn't in any case write in the models.

Fix Description

A filter on "available_in_pos" property has been added to the search, and,
because we now only search on already availaible products, rewriting on this
fields isn't necessary. We then decided to add an optional parameters to the
_addProducts method, set to true by default, which allow us to set (or not)
the products as 'available in POS'.
