[FIX] mrp: removed operation types and stock rules

When user uninstall the module 'Manufacturing' the relevant records are not
deleted from the Operation Types, Transfers and Stock Rules.

To produce in sass-16.2:

- Install 'Manufacturing' module
- Create mrp order and validate it.
- Now uninstall 'Manufacturing' module.
- Operation Type 'Manufactuing' is still showing. (14.0 to master)
- Go to 'Inventory' and click on 'Receipts' and remove all the filters.
- Another way > Create a new 'stock.picking' with 'Operation Type' as
'Manufacturing'
Error: A traceback appears: 'Wrong value for stock.picking.picking_type_code:
Manufacturing'

Fixed this issue by updating the code of the picking type and archiving it after
uninstallation of module using 'ondelete' function.
