RESTRICT AUTOMERGE Fix unable to send file via OPP

Bluetooth app will indicate BluetoothOppReceiver to receive
device picker intent. But for fix the security issue we
removed the setClassName() method in ag/14111132 to avoid attack.
It causes BluetoothOppReceiver cannot receive the intent.

This CL will compare to calling package name with launch package name.
If they are not equal, the setClassName() will not invoke.
