feat: make preconditioning failure available (in API)

The preconditioning element has an interesting field called
"failureCause" which reports error conditions like opened doors, battery
low state etc preventing the preconditioning to run. These errors are
interesting, so make them available in our API.

This field was removed in 619cefd, not sure why, so add it again.

Fixes #760.
