[BUG] Crash when trying to move item using TalkBack action

[ClaytonTDM]

Describe the bug

If you try to move a widget using TalkBack actions, Lawnchair crashes.

Steps to reproduce

Steps to reproduce the behavior:

1. Hover over a widget
2. With TalkBack enabled, press with 3 fingers to open the actions menu
3. Double-tap the first item in the list, "Actions"
4. Double-tap on "Move item"
5. Move your finger to the widget, which is in the incorrect position
6. Tap with 3 fingers at once
7. Double-tap "Actions"
8. Move your finger to "Move item" and double-tap, and Lawnchair will crash

Expected behavior

Lawnchair should give an option to move the widget instead of crashing.
