[FIX] mrp: remove unnecessary transit line on MTO overview

When displaying the MO Overview of a MTO product, "In Transit" lines
would be displayed for MTO components until the component was consumed.
Now checks whether the component is ready to be consumed (i.e. its
reservation is the MO itself, not a picking before) to know if it should
display the transit line or not.
