Test Run status calculation is wrong with the Data set and custom Test Statuses.

Description
If a Test Run has a Data Set and Custom Statuses then the test run status calculation is wrong.

The test Run status changes to the same as the custom status when we change the status of one iteration.

Pre-conditions

Create a Custom Test Status.

How to reproduce

1. Create a Test with the data set.
2. Execute the Test.
3. Change the status of the first iteration to the custom created status
4. Then overall status is changing to custom created status

Actual result/Attachments
Overall Test Run status is changing to custom created Test status instead of Executing even though it has multiple iterations. 

Expected result
If Test Run has multiple iterations then the Test Run Status should be Executing when we give a custom status for one iteration.
