[16.0][BUG] When migrating the rma module from v15 to v16 about rma

[pleirb]

If I delete the migrations folder (which was added 2 weeks ago by @mt-software-de and @victoralmau) of the rma module, the migration from 15 to 16 is done correctly

[mt-software-de]

The commit what was used was cherry-picked from v14.
And was not ready to merge yet.

But to help here, the fields rma_in_type_id and/or rma_out_type_id not set on the warehouse, the are used and mandatory to create the new rules for the rma proc run.

Within the migration we have to ensure, that those fields are set.
Therefor _create_or_update_sequences_and_picking_types needs to be called at the migration.
This would then create the missing stock.picking.type.
But to ensure that no other stock.picking.type is changed, we have to overwrite _get_picking_type_update_values and checking the context value rma_post_init_hook. Like it is done in

rma/rma/models/stock_warehouse.py

Line 149 in 6713de3

def _get_routes_values(self):

rma/rma/models/stock_warehouse.py

Line 185 in 6713de3

if self.env.context.get("rma_post_init_hook"):

We will check it soon. Thanks for the extra info, Michael.

Thanks @mt-software-de I have configured all the warehouses so that the rma_loc_id, rma_in_type_id and rma_out_type_id fields have a value and after running the migration again this error no longer occurs
