Remove reference doesn't work natively with Reference.ref()

[pgressa]

When trying to remove reference by using Reference.ref() then it fails:

References ref = ....
repo.git().references().remove(ref.ref())

Error message:

{"message":"Reference does not exist","documentation_url":"https://developer.github.com/v3/git/refs/#delete-a-reference"}

Root cause: The uri is not correctly constructed as it contains two refs key words:

https://api.github.com/repos/ORG/REPO/git/refs/refs/heads/BRANCH/BRANCH
