bug in the http_client.rb code in 4.0.0 build_request method - modified request is not returned if params not empty and submit method allowed

[qvrb]

in the following code the request object is not modified or returned in the case where the SUBMIT_METHODS & params not empty in http_client.c

62     def build_request(method, uri, params = {})
63       # Construct the HTTP request.
64       raise MethodNotAllowedException unless ALLOWED_METHODS.include?(method)
65
66       request = Class.const_get("Net::HTTP::#{method.to_s.capitalize}").new(uri.request_uri)
67
68       request['Accept']        = 'application/json'
69       request['Authorization'] = "AccessKey #{@access_key}"
70       request['User-Agent']    = "MessageBird/ApiClient/#{Version::STRING} Ruby/#{RUBY_VERSION}"
71       if SUBMIT_METHODS.include?(method) && !params.empty?
72         prepare_request(request, params)
73       end
74       request
75     end

The code on line 72 should read request = prepare_request(request, params)
