This is the first step to a more comprehensive handling of company-dependent
fields which are ir_properties.
With model-specific access rights, users should be able to read/update a
company-dependent field no matter their access rights on ir_property.
Before this commit, a user having access to res.partner, but not to ir.property
couldn't write on property_account_receivable/payable just because he couldn't
write the corresponding ir.property. After this commit, he can.
