widgets: fix insanity

Fix two issues where Auxio's widget could not be resized to a single
cell, and another where covers would not load into the widget.

The first is caused by a random, subtle change that completely changed
up the minHeight size calculation regarding widgets. Thus, we need to
lower it for android to recognize it still as 1 cell. I cannot believe
we can't just specify the specific minimum grid size that our widget
takes up, like you know, iOS did, nearly a decade after widgets were
first added in Android.

The second is an absurd race condition stemming from me hitting the
RemoteViews memory limit. Turns out my cover bitmaps were simply too
big. Getting them below the limit requires me to resize them to a puny
~500 pixels. Why can't we just render our own views into our widget?
You know, like iOS did, nearly a decade after widgets were first added
to Android.

Nah, screw modernizing the broken widget API. Let's just vaguely copy
iOS widgets because we have to while not fixing a single issue plaguing
widget development on this OS. That way some google engineer can get
promoted faster.
