fix(mobile): unfolding the Duo shows the sidebar as the split expands

UIKit applies the split's preferred display mode while a collapsed split
expands, before the new width reaches JS. The collapsed split asked for
secondaryOnly whenever a detail was open, so unfolding first hid the
sidebar and then slid it in once JS saw the wider window.

A collapsed split now carries the display mode the expanded split will
use, so the sidebar arrives with the expansion.
