Fix back stack didn't perserved when Files Activity launched by Setting storage then back case.

Browse Source 
Due to FilesActivity set "android:documentLaunchMode="intoExisting", it will create
new task when launched from Storage Setting page.

When select FilesActivity task from recents & press back key, it will not back
to settings page.

Using startActivityForResult to set task as source task can fix task separated case.
