added a conditional atatement because during simple_autosubscribe there is only one service level, so register dialog window to select service-level does not exist
the tests were failing because of the improper usage of data returned by data-providers. The data providers were modified and had to be renamed accordingly
The dataprovider failed as the system was unregister. Added a conditional statement to verify if the system is registered
The newly refactored tests had repeated data-provider so had to remove one of them
the tests had to start with system in unsubscribed state
