Workaround when sending a new file for Windows Phone.
Workaround when sending a new file for Windows Phone.

When requesting the properties for a newly sent file,
Windows Phone does not support requesting properties
by depth. To work around this issue, I have changed
the ptp_mtp_getobjectproplist() to request the properties
of one object only instead of all the objects below it in
the hierarchy.
