Puppetfile installed modules are not purged

[adrienthebo]

If a module is removed from a Puppetfile it won't be purged. Doing an r10k synchronize should purge all module directories of stale modules.

This also hurts if you switch a module from forge to git:

[R10K::Action::Module::Deploy - ERROR] Could not synchronize /etc/puppet/environments/strings_attached/modules/mcollective: "git clone --reference /var/cache/r10k/git---github.com-puppetlabs-operations-puppet-mcollective.git git://github.com/puppetlabs-operations/puppet-mcollective.git /etc/puppet/environments/strings_attached/modules/mcollective" returned with non-zero exit value 128
