[FIX] pos_cache: eval domain before sending it to server

Since changes made on 'product.product' model in rev: 30e4d89a62c21e76db651ca54f8c132b96e7668d
the domain is not represented as a string, but as a function, and that
leads to error as the javascript function is sent to the server instead
of a string representing a domain.

So we check the type of domain to see if we have to evaluate a function
or send the domain as a string
