Fix #8093: Build+Refit changed game-state in command test run, and thus caused desyncs.

Browse Source 
Use DC_AUTOREPLACE for actions that shall be reversibe, in this case:
- Do not rearrange free wagons in test-run.
- Do not discard OrderBackups.
The latter was not triggered by actual auto-replace, since it does not set a 'user'.
