Openrct2: Queue line paths broken when using some track designs

When the track design contains queue line paths, they are in some instances not built as expected. I guess this has to do with the improved queue line path building in OpenRCT2 (which by the way is awesome 😄).

• [ ] Reproducible in RCT2 (vanilla)?
• [ ] Multiplayer?

Steps to reproduce:

1. Start a new game with the park "Gravity Gardens"
2. Build a new Side-Friction Roller Coaster
3. Build "Creaky Dips" somewhere
4. You can see that a large part of the queue line path is just a closed loop and the actual path is just 1x1

Maybe this isn't fixable without breaking compatibility.

This sounds fixable. Might just have to add a hack to say don't change the path connections when placing the track design.
