When posting inventory during a manufacturing order,
all raw material and finished product moves are used,
also those done from a previous post inventory.
This is no problem for the moving of quants because
a filtering is done in the move_validate method,
but it is a problem for the price calculation in
mrp_account and for linking the consumed/produced_quant_ids
of the quants of the raw and finished moves.
Before this fix, it would calculate already consumed materials
a second time in the price of the finished products and would
link quants produced with previously consumed quants (and vice versa)
when doing a second post inventory.
We add a test to show the issue.
