Ryan Brown 958ad7726a Properly handle user selection of None as vars_files (#31313) ... * Properly handle user selection of `None` as vars_files In a playbook, if a user has a playbook like: ``` - hosts: localhost connection: local vars_files: tasks: - .... ``` Then `vars_files` will be none, and cause a `TypeError` in vars-manager when it tries to iterate over them. To avoid this, I changed the getter to either send back the vars files from the user, or an empty list when the user passed `None`. * Only replace None with an empty list, not all falsey values * Catch error when vars_files isn't iterable * Move whole `for` loop into try/except and catch TypeError * Line length		2017-10-09 11:27:50 -04:00
