Set state to CLOSED when unfolding with a HUN visible

Unfortunately, HUNs set the state to OPENING, so if the user unfolds
with a HUN showing, some necessary state updates will be skipped when
the user pulls down the shade, because it does not switch to the OPENING
state. Most notably, QS will never be set to visible, causing
b/324642496. The least disruptive fix is to tweak the state only when
unfolding, because there are cases in NPVC that specifically define the
HUN state as the shade being expanded, implying that the bad state could
be load bearing and too risky to repair more broadly, especially when
we already have a flag under development that completely deletes this
class.
