Referendum 7 (passed by the Council and the community) failed to come into place given the parameter to be executed after was 0 (zero) instead of 1.

```
let when = match when {
			DispatchTime::At(x) => x,
			DispatchTime::After(x) => now.saturating_add(x)
		};

		if when <= now {
			return Err(Error::<T>::TargetBlockNumberInPast.into())
		}
```

0 fails to check, but 1 would happen next block after the referendum is passed. I am proposing the exact same motion to Council and requesting TC to pass to referenda queue in the same way as before.

 Schedule the currently externally-proposed majority-carries referendum to be tabled
 immediately. If there is no externally-proposed referendum currently, or if there is one
 but it is not a majority-carries referendum then it fails.

 The dispatch of this call must be `FastTrackOrigin`.

 - `proposal_hash`: The hash of the current external proposal.
 - `voting_period`: The period that is allowed for voting on this proposal. Increased to
   `FastTrackVotingPeriod` if too low.
 - `delay`: The number of block after voting has ended in approval and this should be
   enacted. This doesn't have a minimum amount.

 Emits `Started`.

- Referendum 7 did not happen because it was set to happen at 0 instead of 1.
- The code needs to be changed so that it checks for 1 instead of 0.
- The proposal is to pass the same motion to the Council and the Tech Committee.
- The Tech Committee needs to add it to the referenda queue.
- The proposal is to fix the code and make the referendum happen.
