[FIX] website_crm_partner_assign: Copy lead geolocation to created partner

Purpose
=======

The module website_crm_partner_assign has its own partner_longitude
and partner_latitude values that are resolved independently, when the
linked partner doesn't exist yet.

So when a lead is turned into an opportunity and a partner is created,
the address info is copied to the new partner, but not the geolocation.

In case these partners are supposed to be geolocalized (for example
on the FSM application), the geolocation will be recomputed despite
the fact that this information was already available at the convertion
time.
