[Genhis][2.0.75] Item cannot be launched to orbit manually

[thesixthroc]

It seems that since version 2.0.74, there is broken functionality for some items with `send_to_orbit_mode = "manual"`.

Attached is a save in which such an item (`cerys-hydrogen-bomb`) is placed in a rocket inventory. Clicking the silo, then 'Deliver cargo' and 'Orbit', has no effect and the rocket does not launch, so players cannot complete the planet.

Thanks for the report. It seems that I broke manual item launches for items with no launch products when I fixed 132527. It is fixed for the next release and covered by an automated test.

Thanks, much appreciated
