Properly animate canceled deep shortcut drag back to original icon

- Added getFirstMatch() instead of using mapOverItems() (was a bit cleaner using ItemInfoMatcher)
- Match based on package name / UserHandle for deep shortcuts case

Test: drag deep shortcut from taskbar icon, inside folder, inside all apps; drag regular icons as well
