When computing the price of a product through a pricelist item, if the
item was based on anotherp pricelist, the dates and uom weren't given to
the subsequent method call.

As the majority of the calls to those pricelist methods put all their
arguments in the context, it wasn't noticed until now.

Functional example:
Pricelist A:
Rule A1 : 10% discount on Pricelist B, from day 3 to day 6.

Pricelist B:
Rule B1: 5% discount on Sales price, from day 3 to day 6,
Rule B2: 10% discount, from day 7 to day 9.

If today was day 8, the call to pricelist(A)._compute_price_rule(day=5)
would use rules A1 and B2, but should have used rules A1 and B1.
