When launcher loads, it fetches the list of apps twice, once for
loading all-apps and again for updating icons. Instead reusing
the previously fetched apps list.
Also moving the icon loading in a separate package for further
generalization

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)
