Handle older git archive commands

Older git archive commands create tar archives even with a tar.gz
extension. So change it to always create tar archives and have
the install_role method cope.

Removed ssh roles from the test case as they don't work unless
you can connect to bitbucket via ssh and have your key there.

Corrected a minor typo in error messages
