Issue description:
If I start a recipe on the space platform, request resources for that recipe and then change out of that recipe, the request from the rocket silo still persists.

Steps to reproduce:
1. Choose a recipe on a space platform
2. Set material requests for that recipe
3. Change the recipe to something else

Results:
The request for material stays active

Expected:
The material requests should get nullified if the recipe is changed

Thanks for the report. For 2.0.15 i made it so that when recipe is changed then item requests are revalidated. I checked that when clearing recipe those requests are gone, not testing what happens when changing recipe from one valid recipe to another.
