Bug: 36718342
1.The flicker was also happening partially because notifyWidgetProviderChanged
callback also made the entire widget list to update in addition to
packageManager update.
2. Now that adapter calls notifyItemInserted, Removed, the recycler
view uses it's internal animation to elegantly move items or insert
them. (added benefit!)
3. Added tests for WidgetsListAdapterTest
$ adb shell am instrument -w -e class com.android.launcher3.widget.WidgetsListAdapterTest com.google.android.apps.nexuslauncher.tests/android.support.test.runner.AndroidJUnitRunner
com.android.launcher3.widget.WidgetsListAdapterTest:.
Time: 0.337
OK (6 test)

Indexer depends on the locale and should be created when ever the config
changes. Moving the widget indexing to the adapter (similar to allApps)
which gets created whenever the activity is recreated.
This fixes the bug where widgets indexing breaks if locale changes while launcher
process is alive
Also fixing the bug in widget model cloning where the HashMap was not cloning
the underlying ArrayList
