[FIX] crm_claim: _claim_count

When clicking on the smart button "Claims" of a contact, it shows
a tree view with all the claims of this contact and his children(because
the domain on the filter is [('partner_id','child_of',self)]).
So the function _claim_count has to return the sum of the # claims
of a contact and the # claims of the children of this contact.
