FP2-627: The MTP function is invalid at guest mode.

When device is connected to host computer in MTP mode and new
user is added the contents of internal storage and SDCard are
swapped.

The issue is because in new user case the volume paths are set
in reverse order and getting of storage id from framework is
based on the the index and not path for now. This results in
swapped storage_ids for internal and external storage.
