[MOV] mrp: check finished lot in mrp module

Consuming product tracked by lot (or serial number ) to produce product
also tracked must ensure the link between the two lots (consumed and produced)
is always set. This test is not done in community version while there is
one in the enterprise conterpart (mrp_workorder module). This commit
move this test to the mrp module to have it everywhere
