[2.0.15] Manually connecting rolling stock clears train schedule/group

[Vulcan]

Manually connecting rolling stock in a locomotive resets the locomotive's group and removes some or all stops from the schedule.

Steps to reproduce:
- place some cargo wagons
- place a locomotive unconnected to the wagons and give it some stops
- get in the train and connect the wagons by pressing 'J'
- the schedule is missing one or all stops from the schedule

Thanks for the report. When merging trains one of the two sides has to be picked as what the merged train will have schedule wise. The most-recently-modified train wins.

Thanks Rseding, that makes sense but I still feel like this is very unintuitive behaviour when one of the merged 'trains' is just a cargo wagon.
In my mind, the locomotive is the thing with a schedule and the wagons are just boxes on wheels, so placing down a box on wheels and it then overwriting the schedule of the locomotive I'm driving feels very weird.

Wouldn't it make more sense to choose the train that you are driving?
