Nvidia performance mode enabled, the Shell still show useless "Use dedicated card option"

[Didier Roche-Tolomelli]

Once you select manually performance mode in nvidia-settings, GNOME Shell shouldn’t display "Use dedicated card option".

Launching directly any app, in this mode, starts your application using the nvidia card already.
