[FIX] mrp: support multi-operation type allocation report

Steps to reproduce:

- toggle setting `mrp.group_mrp_reception_report = True`
- create a new 'mrp_operation' operation type and activate
  `auto_show_reception_report` for this operation type
- create a delivery of a product (qty > 1)
- create 2 MOs for the product to deliver, one with the new operation
  type and one with the built in operation type
- try to "Mark as Done" both MOs (from the list view)

Expected result:
MOs are marked as done, only 1 of the MOs shows up in the allocation
report for the delivery

Actual result:
Singleton access issue
