Fix ansible use of filters and tests

Ansible 2.9 requires the use of "version" as a filter and
"version_compare" has been removed. Also tests cannot be used as
filters which means we cannot do when: foo | test and must do
when: foo is test instead. Make these fixes.

Both changes should be backward compatible to ansible 2.5:
