If an HTTP connection returns unsuccessfully, gorequest will return nil for the response object, so attempting to view the StatusCode will trigger a SIGSEGV panic.

It is therefore only safe to make that check after ensuring that the response is non-nil

I have a code snippet that I used to track down the root of the panic, as well as verify that this fix works: https://gist.github.com/benjdewan/4941195e771a42f076383c95aaf796d8

When we hit this corner case the errors gorequest may return will never be properly processed by ProcessErrors because they are not returned by the compose API, but from within the gorequest library or one of its dependencies which is why the new code does not invoke that method.
