deploying to gh-pages fails when no gh-pages branch

[samccone]

for now manually creating a commit on gh-pages and then deploying works, it is just the first time that it fails.

here is the stack

✘ {"message":"Invalid request.\n\nExpected data to be of type \"string\"; value was: nil.","documentation_url":"https://developer.github.com/v3"}

Ah ok nice catch, thanks! I'll try to get a fix in for this shortly, shouldn't be too tough.
