The claim_count field was incorrectly added into addon stock instead
of addon claim_from_delivery. The commit adding the claim_count field
in stock.py was reverted, but claim_count is still needed in
claim_delivery_view.xml.

This module had been inheriting stock.picking, and redefining the
"partner_id" column. Moreover, it has been redefining it with store=False,
which broke the parent stock.picking.
That's redundant, skip the whole class.
