Don't nowrap() empty lines.

Summary:
f4d0dca introduced the nowrap control codes, but it was applying them before
the output was checked for empty(). That meant that empty lines weren't empty
anymore, and a lot of blank space got printed in e.g. `buck test --all`. Moving
the nowrap avoids this problem.

Test Plan: `buck test --all` no longer prints a lot of junk.
