Fix some sonars in policy-models

Fixed the following sonar issues in some of the project directories: - use assertNull, assertEquals, etc. - swap assertEquals arguments - extract a constant - don't invoke toString() in logger calls - TODOs - generic types Issue-ID: POLICY-2714 Change-Id: Id8803f9bf617ea9fc173a67b8606600709b55bdc Signed-off-by: Jim Hahn <jrh3@att.com>
