front: fix pathfinding error message bubble

setFailure() doesn't accept a "message" property. Additionally,
the "pathfindingError" translation needs an "errorMessage" property.

To reproduce:

- Select a train in small_infra
- Switch to another infra (e.g. France)
- Open the "Create new train" modal
