Updated error message as per #322

It would probably be better in the long run if a gist was created in the hanami repo or a blog post in hanamirb to properly explain the console issue, but I think this will suffice for now given that the ROM upgrade is on its way.

This addresses #322 (in title here but putting in this comment so it's referenced in that issue)

Sorry for the delay here. I don't think we should link to #250 in the error message since it's only tangentially related (it's for dropdb not createdb). Seems potentially more confusing than helpful.

Can we change the error message to just createdb: database creation failed. If the database exists, then its console may be open. ? I think that's clear enough. What do you think, @wjdhamilton?

Hi Sean, yes. Um...only one small problem which is that I mistakenly deleted my branch in the intervening period. One of those times I really should have read the warning message. Anyway, I will effect those changes in a new repo and get the pull request in.

No problem! It's a small enough fix and GitHub cached the diff (on the Changes page) so you can re-do it from that.
Thanks!
