[FIX] web: re-introduce many2one_reference field and formatter

This field type has been forgotten in the PR that converts web
fields to wowl, probably because it wasn't tested. This commit
defines a Component and a formatter to use for that field type,
in wowl views, s.t. we no longer rely on the legacy implementation.
