switcherPopup: Fix scrollable check

Browse Source 
When commit c6cea277e replaced Shell.GenericContainer, the check
whether the required width exceeds the avilable width was changed
from using the minimum widths of items to the natural width of the
scroll view.

That doesn't work correctly, as the *natural* width may well exceed
the actually used width: SwitcherList bases its width request on
children's minimum sizes to force labels to ellipsize.

Fix this by using the minimum width of the scroll view's child instead.
