Warn/fail if a proposal is created in `Review` (or later) status

[SamWilsn]

Downstream tooling requires each proposal be merged as a Draft first, then move to Review. If the proposal appears first in Review, it messes up statistics.

eip-review-bot currently flags any such proposals as e-consensus and requires half of all editors (rounded down) to approve. Would you prefer alternative behavior?

I suppose, we can use a message for the author/reviewer with the "reason for the flag" will be helpful.

Something like "No Draft available in EIPs/ERCs repository" for a PR requesting to be added as a Review instead of Draft. It will help authors & reviewers of PRs like this and it could be merged with an appropriate status.

If possible, this check should be made available for all statuses. As similar issue of missing a status (Review) was also noticed here with a Meta EIP.

That last one is odd and shouldn't have happened. More helpful messages are definitely something that would be useful.
