[FIX] base: add commercial_company_name to the depends

Before this commit: if you add a custom one2many field to the
'res.partner', like x_related_commercial_partner_ids, that is related to the
`commercial_partner_id` in the`res.partner` model, it won't update the
display name of a contact in case of changing its parent_id name.

Here are the steps to reproduce the problem:
 1. Create a new custom field with these values:
   a. Field Type = one2many
   b. Model = Contact
   c. Related Model = res.partner
   d. Relation Field = commercial_partner_id
 2. Create a new Contact that is the "Company" (e.g. "My Company")
 3. Create a new Contact that is the "Individual" (e.g. "My Name"), and
    put the "My Company" as its parent_id.
 4. Now the display_name is "My Company, My Name" which is correct
 5. Change the company name to "My new Company"
  -> display_name won't change, and is "My Company, My Name"

The solution is to add the 'commercial_company_name' to the
`display_name` depends.
