Treat all apps predictions as all app icons when animating icons to their original position

Taskbar all apps predictions were being ignored when animating a cancelled drag to their original position. This was causing a null pointer since they no longer had a view parent that could be used. These icons will now animated to the taskbar all apps icon.

Fixes: 236669335
Test: cancelled drags of taskbar icons, predicted taskbar icons, taskbar all apps icons and taskbar all apps prediction icons
