many_to_many relation throws deprecated warning

[Sadrak]

DBIx::Class::ResultSet::search_rs(): search( %condition ) is deprecated, use search( %condition ) instead

I traced that warning down to this line in _save_columns:
$dbic->$accessor($value);

After chatting with the DBIx::Class-Stuff i get this helpful answer:

$obj->m2m_rel just calls $obj->search_related($link_rel)->search_related($foreign_rel, @_, %attrs)
so that becomes ->related_resultset($foreign_rel)->search(1001, %attrs), which is deprecated

And an solution
in that case it should be ->set_m2m_rel({ id => $_ })

But i thinks this must be configurable in HTML::FormFu::Model::DBIC. But i hope this many information is enough to fix it.
