Describe the issue

When building backwards from a large half loop the default track piece selected is another large half loop, but it is invalid if you build it, and the train will crash if it goes over it. The inverted state of the new track piece needs to be swapped.

Steps to reproduce

Build a large half loop, delete the connecting piece at the top and then build backwards from it.

Research direction

No source file or test is named. Reproduce the issue by building a large half loop, deleting the connecting piece at the top, and building backwards; then trace the flying coaster track-building path for how it selects the next large half loop. Done means the selected piece has the correct inverted state and the resulting train does not crash.
