[SU12B] AI Changes - Non departing SimConnect Traffic [Fix confirmed]

Hey Slyvian @FlyingRaccoon the issue with non departing AI (when airport
vehicles set to 0%) seem to be fixed as well. But i see there still some room
for impreovement. At the moment (SU12B) the slider is set to 0% and the
pushback truck is not spawning for the sleeping injected airplane, but will
get spanwed by the Sim when the airplanes prepars for pushback. Meaning if if
the user sets 0% airport vehicles the sim still creates some - no big issues
for us from developer point of view but might eb something you guys can look
