Title: JENKINS-19500 Fix: Unable to delete slave for spot request that no longer exists.

Stops the following error from occuring: https://gist.github.com/mriddle/e2dd024c992b7de35552

Enables the user to delete a slave entry for a spot instance that no longer exists by returning null when AWS is unable to find the spot instance for the given request ID.
