Database setup step in wasp start reports success even when it fails

[Martinsos]

Run wasp start without database running, for waspc/examples/todoApp. Database setup step will print errors to stderr but it won't recognize failure. It should recognize failure and not report success! I am not sure if we should fail wasp start at that point or not, but even if not, we need that error to be visibly reported and obvious, because it will cause other errors messages below that make you completely miss the real source.

Btw, it does stop with nice error message in wasp db migrate-dev, because there we have that precondition / require check.
