[containments/desktop] Stop hardcoding applet handle tooltip position
requested to merge ngraham/plasma-desktop:stop-hardcoding-widget-control-handle-tooltip-position into master
Doing this caused the tooltip to overlap the configure button when the widget was rotated 90 degrees horizontally, and therefore made that button inaccessible.
The ToolTip already has code to dodge other UI elements and disappear when the mouse overs over it; let's let that code work (which it does) and just remove the hardcoded position overrides here.
