[2.0.41]Blueprint system doesn't copy fuel already used

[RenKuro]

Prerequisites:
Section of train tracks with at least one station

Steps to reproduce:
1. Place train down not on train station
2. Insert a singular unit of fuel
3. Make train go to the station thus consuming fuel and having it as a red bar
4. Make a blueprint of this setup that includes train

Expected behavior:
Single half consumed unit of fuel is displayed as Vehicle fuel

Current behavior:
Fuel that is in half used state is not considered Vehicle fuel for purposes of blueprinting

Note:
I understand that considering this half used fuel may lead to overflowing requests where parked trains request 4 Nuclear fuel where only 3 can be inserted. Nonetheless this is annoying when planning train features and needing to insert 2 pieces of fuel to actually blueprint required fuel.

It is copying the items in the fuel slots, if the last item has been consumed there is nothing to copy.
