Fix bug where widgets are inflated in the wrong orientation.

The bug is that in onResume, the context may tell us the wrong
orientation.

As a workaround, we store the orientation that the Launcher
is created with, and we use that orientation to check whether
we actually need to reinflate the widgets.
