[FIX] mrp: carry over origin from source move in 3-step mfr

Behavior prior to this commit:

- when the warehouse uses a 3-step manufacturing process, if I create a
Sales Order, the MO generated does not show the SO# as "Source", instead
it shows the MO#

Behavior after this commit:

- the MO source shows the SO# (similar to how it works when using the
2-step or the 1-step manufacturing process)
- the origins are assigned thus:
  - Delivery Picking = SO name
  - Post-prod Picking = SO name
  - MO = SO name
  - Pre-prod Picking = MO name

Note:

- there is no implementation change in this commit - we just ported the
test from the original commit in 13.0 (the behavior in 14.0 was already
OK)
