I don't think that GetFilesChanged should be creating directories on the device.
That should be left to PushIfNeeded. I'm also not sure that this fix would work
if the device path was more than one directory deep.

I think you're right that this only triggers on the code path that pushes
individual files in PushIfNeeded. Perhaps we should be creating directories
there? (although that could mean more adb round trips, which we'd like to avoid)

I agree that this should not create directories on the device. Can PushIfNeeded
create the directory instead?

Done.
