Title: Patch to make GetConfigurationValues tolerant of values provided by third party vendors that don't have an Id or Url associated with them

I signed up for CloudAMQP (RabbitMQ), and was given a config value without an id or url. GetConfigurationValues was throwing a null reference exception because the Url returned with the value from AppHarbor is null. With my change, the API is now tolerant of such missing data, but obviously if I attempt to subsequently retrieve the variable with an Id of 0, I will get a null value back.

If you use your browser and pull https://appharbor.com/applications/YOURAPP/configurationvariables/0, AppHarbor replies with:
{
"key": null,
"value": null
}

Also, when I went to run the tests, it looks like there's a lot of broken tests. I didn't write a test for my change.
