The `ipfs init` command prints out a ton of information which can make it hard
to spot errors. Print a newline before these errors

We could do this for every command but there are some tricky edge cases:

1. This would look funny if there's no other output.
2. It might mess break tools parsing the output (not expecting empty lines).
