PerformanceManager: Don't force powersave mode with powersave profile

Browse Source 
Allow to use the powersave profile without enabling the powersave
mode, but force the powersave profile when enabling the powersave
mode. This makes the profile a bit more useful since unlike the
the powersave mode it has no direct UX impact (e.g. animations),
yet it allows to reduce the power consumption.
