Subject: Fix bug in ensure => absent

The insync? method wasn't accounting for a condition where the state was
absent and the desired state was absent. This manifest itself in puppet
runs that would constantly output the following after setting
ensure => absent.

I added unit tests for the vcsrepo type and then fixed the code.
