[2.0.49] disabled_by_script rocket silos still try to fulfill requests

[Quezler]

When you disable a rocket silo by script it'll still allows the silo to receive a new robot delivery order as well as trying to launch when in automated mode.

In alt mode you can see that in both instances the items move to the cargo pod of the rocket but then it just stays there, and the platforms will be stuck "waiting for a rocket to arrive" that might never come.

Steps to reproduce:
- load save
- select silo
- /c game.player.selected.disabled_by_script = true
- put a stack of space platform foundations into the logistic chest - or - disable the transitional request checkbox on the silo and put the stack in manually
- notice in alt mode the items are in the cargo pod
- go to the platform
- add a schedule to any space location
- notice the waiting for rocket to arrive status
- notice the rocket silo won't ever do anything

Expected behavior:
- disabled silos cannot be candidates for new bot item deliveries
- disabled silos cancel any existing bot item deliveries (multiple solutions possible, this one seems the most logical)
- disabled silos cannot decide to launch when their contents match a request
- if the rocket is already in a launching state it'll be the mod's responsibility to wait before disabling the silo by script

Thanks for the report. This is now fixed for the next release.
