Fix some oopsies!

[Chew]

As this is a beta, I have discovered and patched some bugs you may have run into.

e4a2382 - Fixed unnecessary String wrapping. If a JSON string was provided, it would be wrapped, causing an invalid JSON to be returned. Now, it will only be wrapped if there's no response.
c57672a - Also fixed response headers for some errors. They would sometimes show up in the request, which isn't good either.

Thank you for using the plugin!
