"Rename" and "Clone" buttons for run configuration are disabled

1. Have two kits set up in Creator.
2. Open a CMake-based project and configure it to use exactly one of these kits.
3. Go to "Projects" mode.
   The one configured kit is highlighted, the other is grey.
4. Click on the name of the other kit.
5. Click on "Run" for that kit to show its run configuration.
   Creator configures the project with that kit and automatically creates a run configuration with the project's name. The run configuration can neither be renamed nor cloned because the respective buttons are disabled.
6. Show the first kit's run configuration.
7. Show the second kit's run configuration again.
   Now the buttons are enabled.

Creator should have enabled the buttons right after it finished configuring or even earlier. For a qmake-based project, they seem to be enabled all the time.
