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`.

Weight: `O(1)`

- **Problem Statement:** Referendum 7, approved by the Council and community, failed due to an error where it was set to execute at 0 instead of 1.
- **Significance:** The incorrect parameter setting prevented the implementation of Referendum 7, impacting the intended decision-making process.
- **Proposed Solution:** Adjust the parameter setting to execute Referendum 7 after 1 unit of time instead of 0.
- **Expected Outcomes:** Successful execution of Referendum 7, ensuring the intended decision-making process is carried out effectively.
