[FIX] mrp: fix show mass produce backend/shopfloor

Shop Floor introduces a restriction on how the show_serial_mass_produce
flag is computed :
the components cannot consist of more than 1 lot/serial.

However, this has a side effect on backend views where it is still
required to have full 'Mass Produce' functionalities.
