Fix gnsync unicode error

[wbushey]

Just started using GeekNote, and I'm really liking it. Ran into #109 while syncing some notes; this fix has worked for me for the last few days.

Hi @wbushey, thanks for the fix. Would you mind addressing the Travis failure before I pull? Thanks.

@wbushey, also in my build I'm seeing mock is missing. Could it be a missing requirement or some other setup change that's required?

I added mock to requirements.txt, so when running the tests locally, you're going to need to first run pip install -r requirements.txt. That should take care of finding mock.

As for the error in Travis, I think I see what is happening. I need to mock out Storage().getUserToken() in the test I added so that GNSync can be instantiated. I should be able to do that pretty quickly.
