ORA-55518: Mining across reset logs

Cause: Flashback Transaction Backout cannot work with missing changes. This error is thrown if we walk across a reset-logs branch, where we might have missed changes.

Action: If the user knows that the transaction happened in the current reset logs branch, then the SCN-hint is possibly incorrect. Provide an SCN in the current reset log branch.
