This was causing a bug in the env module, due to the fact that we now pass variables for the module through the templating engine combined with the fact that we split-up the hostvars and setup variables. As a result, if a variable in the env lookup had the same name as the variable in Ansible, it would try and template itself over and over again until the recursion limit would be hit, at which time an empty string was returned. Fixes #7396
