Test Step status calculation is wrong

Description: When more than one iteration is present with more than 2 Test Steps. The Test Step status calculation behaves incorrectly. 

Pre-conditions: NA

How to reproduce

1. Create a Test Case.
2. add 3 or more Test Steps.
3. Add at least 2 dataset parameters.
4. Add a Test execution and execute it.
5. Change the status of any Test step under the first iteration to PASS, whole iteration status will change to PASS.

NOTE: With lesser Test Steps like 1 or 2, it works fine.
