[FIX] product: import product.template fields using default_code

This rev. is related to 489a96c257

It wasn't possible anymore to perform an import of
a product.template field in a model
(e.g. mrp.bom), while it should be the case.

In the context of an import,
the operator of the name_search is '='.
Therefore, in this super call, the operator was '='
and the name was '' (empty).
In such a case, ('name', '=', '') is added
to the search domain by the base name_search method
(in models.py),
leading to the domain
[('id', 'in', template_ids), ('name', '=', '')]
which will lead to no results.

Forcing 'ilike' as domain is correct, as the actual
name_search, with the correct operator,
has already been performed in the lines above, the
point of this second name_search is to get
the right order along with the right name_get.
