Remove leftovers console.log

After !927 (comment 442337)

I have left two of them, as one should be warning. The other one are in code not very clean.

containments/panel/contents/ui/main.qml
232:                    console.log("Could not create ConfigOverlay:", component.errorString());

desktoppackage/contents/activitymanager/ActivityManager.qml
59:                // console.log("TAB KEY");
62:                // console.log("OTHER KEY");
