v1.3.1

Move failed jinja2 filter to a test (#245)

* Some fixes

* Move failed jinja2 filter to a test

Using failed as a jinja2 filter is deprecated as Ansible 2.5 (current latest
version is 2.9). It is noticed that using it as a filter is leading to failures
on certain setups. Move to using the new way of using failed as a test instead.
