In review of this role it was discovered that we had a duplicate
key within a task. While this is acceptable in Ansible as it will
just use the last key found in a given task it is wrong and should
be removed. In later version of Ansible (2.1.0) a warning is printed
stating something similar to the following:
[WARNING]: While constructing a mapping from xxx.yml, line xx,
column xx, found a duplicate dict key (changed_when). Using
last defined value only. [WARNING]: While constructing a mapping
from xxx.yml, line xx, column xx, found a duplicate dict key
(changed_when). Using last defined value only.
This chage cleans up the role by removing the duplication.
