PUT request with no request_body and error messaging issue

[kmancusi]

I updated to the latest version of this gem (0.3.4), and I'm getting a generic JSON syntax error in my test
Expected BEGIN_OBJECT but was STRING at line 1 column 2 path $

When, before, I was getting a defined message: Request body cannot be empty

From looking over what changed in rest_client_requester.rb, is it no longer possible to have no request_body?

Looks like this was fixed in #158.
