Title: fixes 4725 - fixes deletion of puppet environments with no modules

Without this change, puppet environment would be deleted if for some reason the modules
did not exist on the puppet master in /etc/puppet/environments/

Also new content view versions without puppet modules would not have their environment
changed on the file system to reflect the modules actually in the the repo (none)
