[0.17.43] Bidirectional trains heading not updated on the minimap

[moxian]

1) make a simple two station, single rail network
2) Make a bidirectional train, add both stations to the schedule, switch train to automatic mode
3) Click one of the stations, look at the train icon. Notice that the train chosen as the "heading" does not change, so the train icon travels "backwards" half of the time. This gets mildly confusing, especially on bigger networks.

I probably agree that one clicks on the *locomotive* the minimap should show the direction of the locomotive; however when viewing in the station screen, the locomotive that is shown should be updated each time it changes direction.

I prefer to not change the selected locomotive midway.
