As of v7 search views will replace the value of any `self`
literal in a @context attribute by the name of the
record, whereas it used to be its ID.
This means that the `Pricelist` filter used to display
the product list with a specific pricelist would not
work anymore.
The fix requires a rather hackish name_search()
override for product.pricelist because the display
name of pricelists includes their currency, while
that could be a valid name for a pricelist too.
To avoid side-effects the name_search() override
only picks up the special case used by the
product.product._product_price() method when it
tries to apply the context pricelist, that is
with operator explicitly set to `=` and no extra
domain `args`.
Also avoid useless warning in log by disabling the actual
filtering for the dummy pricelist_id field, whose
only purpose is to alter the context.
Finally, add a default _order for pricelists that is
a bit more intuitive than the default sort by `id`.
An explicit _order was required for the application of
the `limit` in pure SQL, and using `name` seems slightly
better than `id`.
