* When the user is in a v12 room, use different UI to select the last owner when leaving
- Add `LeaveSpaceRoom.areCreatorsPrivileged` to detect when this is happening.
- Import new strings.
- Build the new UI.
- Attach it to a change member roles screen navigation.
* Don't display the `isLastOwner` UI if the user is the only joined one in the room
* Rename `LeaveSpaceState.isLastOwner` to `.needsOwnerChange`. This way, it's easier to understand the difference with the passed `LeaveSpaceRoom.isLastOwner` value
* Add a test for the new check of user not being the last joined member
* Fix paddings in `LeaveSpaceView`
* Update screenshots
