Clover plugin prevents IDEAs internal coverage system

Clover plugin uses a tool window with the name 'Coverage'. This window name is also used by IDEAs internal coverage system. This blocks the coverage function of IDEA.

You have to rename the window ID to a clover specific name.

This is the exception stacktrace:
