Handling added for samesite cookies with httpOnly

After enabling samesite cookies on Google Chrome to support Mashup login, intermittent issues were seen with a non-mashup login where entering the OperatorID and password only resulted in a refresh of the login screen. This was traced to a scenario where an httponly cookie attribute was present along with samesite cookie attributes, and has been resolved by adding handling for a condition where samesite is set and httpOnly is enabled.
