[FIX] mrp: bom with operation duplication

Duplicate a BoM with operations and some BoM line consume in specific
operation. The operations are well duplicated but the 'consume in
operation' field still point to the original BoM's operations.

This commit search for the operation to replace based on the name and
the workcenter_id.
