Fix crash when starting a DM (#6419)

`AnchoredDraggable.requireOffset` was called before it was populated when displaying  `CreateDmConfirmationBottomSheet`, because the keyboard and the bottom sheet were causing conflicting animations related to the insets.

Hiding the keyboard before displaying the bottom sheet seems to fix the issue, and `skipPartiallyExpanded` results in a better UX (and also worked around the issue by itself).
