On Windows, this test depends on  RemovableDeviceNotificationsWindowWin to get
the attached MTP device storage details. I need to refactor
removable_device_notifications_unittest.cc and move the required mock classes to
a common place. I will do this in a follow up CL and enable this test.

+// removable_device_notifications_window_win_unittest.cc to share the
+// mock classes (TestRemovableDeviceNotificationsWindowWin,
+// TestPortableDeviceWatcherWin and TestVolumeMountWatcherWin).
