[FIX] point_of_sale: load pricelists in pos

When we were loading pricelists for POS, we were putting the
base_pricelist of an item in it. It comes from the prveious
implementation on javascript side when it was the reference to the
object that was shared.

As we have put it in python in a dictionnary and we need to serilize the
data.

We also only take the fields we need in POS
