Split-shade: show status bar earlier when closing shade

There was already a mechanism do start showing the status bar given a
certain shade expansion, but it was disabled for split shade.
This would make the status bar only show after the shade had been fully
closed.

I removed the restriction, and now it works as expected.

Test: Manually on-device. See video in comment.
