Android OOP-D: Accept Child LSI Updates While Hidden

Currently, we ignore updates to child LSIs while hidden. This
can lead to cases where the browser never receives the update.

There should be no downside to processing these (this seemed
like an accidental incorrect optimization), so this CL removes
the restriction.
