Steps to reproduce: 

1. Open a source control connected project and keep it open on a machine. 

2. Open the same project from source control on another machine and create a new test list and check in your changes into the TFS. 

3. Get back to the initial machine and pull the latest version of the project. 

Expected behavior: To be able to see the newly created test list in the respective tab. 

Actual behavior: No new test lists appear. In contrast if a new test is created it will appear in the project explorer. 

Note: If the project is closed and opened from TFS again the test list will appear in the respective tab.
