[JENKINS-20446] Git Plugin 2.0 has changed contents of GIT_BRANCH

I've configured a job to clone a repository and use the "develop" branch. With the 1.5 plugin, GIT_PLUGIN was set to "develop". After upgrading to 2.0, GIT_BRANCH is now set to "origin/develop", which breaks my scripts which were relying on the previous value.
