Prevent widget previews from showing empty images.

2016-05-03T22:40:57+00:00

When scrolling through the widget drawer, we submit multiple
AsyncTasks to load and display preview images. On certain
devices, attempting to load these images from
AppWidgetManagerCompat (when we are generating previews for
the first time) on a multi-threaded executor can cause us
to receive empty images. To avoid this, we allow preview
loading from the cache on a multi-threaded executor, but
defer preview generation to a single-threaded executor.

Additionally, the read and write db methods were not using
the same ComponentName output (flattenToString vs
flattenToSimpleString), which was resulting in consistent
cache misses that forced unnecessary preview regeneration.
This has been unified so we properly load from the cache.
