Fix use-after-free when the user hovers over an auto-hide plasma panel in wayland... 

Edge::handle calls showOnScreenEdge, which (on wayland) eventually calls internalShow, which eventually calls ScreenEdges::reserve, which destroys the same edge.
When showScreenOnEdge returns, 'this' has been freed.
Using a singleshot timer allows Edge::handle to return before the Edge is destroyed.
