Title: URIs with trailing ampersands may return old avatars

I have changed my gravatar several month ago,
but [Jenkins Gravatar Plugin](https://wiki.jenkins-ci.org/display/JENKINS/Gravatar+plugin), which uses Gravatar4Java, shows old gravatar.
Gravatar4Java generates URIs with trailing ampersands.
These URIs may return old gravatars.
