When a sale line has a phantom product (mrp kits) the RMA would not be
possible as the wizard couldn't pair the components moves with the
product in the line. With this approach, we can at least return the
spare components of the original kit line.
We also need some hooks to intervine in the main methods, like in
invoicing.
- Now it's possible to open several RMAs in a sale order from the portal
- A new comment button has been added to allow the portal user to enter
relevant information like serial numbers o issue description.
- If the requested operation isn't set no RMA will be opened
- The RMA product qty is now a numeric control with limits according to
the qty available to return
[FIX] rma,rma_sale: fix linter errors
- If no RMA Team is set, we'll assign a default one to the new RMA.
- A sequence is now used to search for the top team and assign it.
- No default user is assigned when it's not in the context (i.e. portal
rmas).
