Fix #11649: Ignore disabling a widget that does not exist. (#11652)

Orders window has different widget layouts depending on vehicle type
which don't all have the same widgets, and therefore it tries to disable
widgets that might not exist.

Restore the old behaviour of ignoring such requests, instead of crashing.
