This typo mistake affects behavior of user.present module function
as it uses 'useradd' linux utility under the hood.
Missing USERGROUPS_ENAB parameter == do not create user groups by default.
This change in behavior of useradd util breaks all states, which are relaying
on creation of user group during new user creation procedure, e.g. set up
cassandra backups.
