title: Unrequest a pre-image when it failed to execute

    description: |
      When a referenda finished the proposal will be scheduled. When it is scheduled,
      the pre-image is requested. The pre-image is unrequested after the proposal
      was executed. However, if the proposal failed to execute it wasn't unrequested.
      Thus, it could not be removed from the on-chain state. This issue is now solved
      by ensuring to unrequest the pre-image when it failed to execute.
