[2.0.72] Rich text tag for invalid train stop shows incorrect name

[asher_sky]

The rich text tag for an invalid train stop displays "Train", but it should display "Train stop" to match the text displayed for a valid train-stop.

Steps to reproduce:
1. create new map
2. go to editor mode and place a train and train stop. shift-click on them to add them to chat
3. see that the rich text tag for the valid train and station display "Train: ..." and "Train stop: ..."
4. open chat, paste: [train=x][train-stop=x]
5. see that the two rich text tags for the invalid train and station both display "Train"
