[FIX] mrp_subcontracting: Allow subcontractor contacts to be used

**Steps to reproduce:**

* Create a subcontractor.
* Create a BoM of type Subcontracting and assign the subcontractor.
* Create a children contact for the subcontractor.
* Creat a purchase order (or a receipt picking) with the children contact of the subcontractor.
* Confirm the document.

**Current behavior:**

Subcontractor documents are not created.

**Expected result:**

They should be created.

**Cause:**

The BoM search is not including possible parents of the partners.

**Solution:**

With the use of `parent_of` operator in the search, we cover both cases of the children
and the parent as initiators of the subcontracting.
