MB-59948 Allow notifications to be changed on >=7.2.3 EE

We previously added a check to ensure we only allow changing these
settings on EE clusters (or CE ones before 7.2.3). The check was correct
but we used a variable `self.enterprise` that was not being populated.
To fix we just tell the `rest_initialiser` decorator to populate it.
