Application Output tab title is wrong after moving tab

1. Create two Console projects: Test1 and Test2
   1. 
2. Run project Test1 and Test2:
   1. 
3. Move tab Test2 to first position
   1. 
4. Run project Test1
5. Bug: The first tab name has changed to Test1
   1. 
   2. 

This bug occurs on Windows and on Linux. I tested it with latest QtCreator 8.0.0-beta1 (Linux) and also with QtCreator 4.15.1 (Windows 10).

It seems the bug is caused by using the wrong index variable in file src/plugins/projectexplorer/appoutputpane.cpp, line 431:
