Describe the bug

I have switched the themes of phpmyadmin and noticed something different in theme: metro. There's something "scheme: win" (basically it is a scheme color and I don't know why is it there and not in other themes and it is not useful information) written after theme name which is not in the other two themes. I think this should be removed.

To Reproduce

Steps to reproduce the behavior:
1. Change theme to Metro
2. You will see the "Scheme:win" thing

Expected behavior

I was expecting the consistency in all the themes.
