DO NOT MERGE Make downloaded apk files in Recent as managed document

ACTION_MANAGE_DOCUMENT only support apk files in Downloads root
but not support downloaded apk files in Recent root. Because recent
root is primary and first root after launch DocsUI. We should make
this also support in Recent roots.
Use docs's authority to check files is from download provider or not.
