Fix a couple of drag and drop issues from transient taskbar
- Don't stash until drag ends, but immediately stash at that point
(regardless of success or failure, though failure will animate to the
original icon before stashing)
- Send transient taskbar's bounds to WM Shell via intent extra such that
they ignore drag events in that region
Test: manual in persistent and transient taskbar
