Bluetooth: Fix Resource Leak in OPP (1/2)

Handle onDestroy in DevicePickerFragment class, which would be
called when user presses back button and does not select any device.
This will send intent to class that called DevicePickerFragment that
no device is selected.

Test: Performed the usecase overnight and see if no crash is observed.
