Regarding of the `display_default_code` context value, `display_name` is
supposed to return the product code or not, eg:
> product.display_name
> '[FURN_6666] Acoustic Bloc Screens'
> product.with_context(display_default_code=False).display_name
> 'Acoustic Bloc Screens'

But since the context was not considered when accessing this field, it would
always return the cached value, which was set from the first time that field
was read, with the `display_default_code` value used at that time.

tl;dr: `display_name` was ignoring the context once cached.

One of the critical issue was that internal code were displayed on the eshop
cart (not the eshop itself), see `name_short`.

Make `seller_ids` `depends_context` of company to
avoid shared cache with different company. The purpose
is to avoid making a SQL search for each `_prepare_seller` and use
the ORM cache (which depends of the company in env).
Also change the `_order` of `product.supplierinfo` to be
determinist and consistent with the `_prepare_seller`.
