[IMP] fields: faster convert_to_record for many2one fields

Browse Source 
Use `env.registry` instead of `env` to get the comodel as a class instead of an
instance, which saves one call to `_browse` each time we access a relational
field.  This saves time because of the cost of `object.__new__` and prefetch
update in `_browse`.
