Describe the changes you have made to improve this project

This PR adds a check for a PresentationSource connected to the PlacementTarget before trying to move a tooltip, as suggested in #165.

Unit test

None.

Additional context

We are using the automove tooltip from ControlzEx in a few places. Some of our users don't use the application on their own machines, but rather connect to their environment via RDP and Citrix. When the RDP connection is closed after using the application for a while, and later reconnected, the application occasionally crashes with the following exception:

System.InvalidOperationException: This Visual is not connected to a PresentationSource.
   at System.Windows.Media.Visual.PointToScreen(Point point)
   at ControlzEx.ToolTipAssist.MoveToolTip(IInputElement target, ToolTip toolTip)
   at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target)
   ...
