Instance creation fails if container already exists

[ssbarnea]

As opposed to docker driver, podman one fails to create an instance if a containere with the same name already exists (not running, only existing).

The fact the original error is not visible even if user adds --debug -vvvv is only making the confusions worse. That error is visible only if user defines MOLECULE_NO_LOG=0.
