Files app: Correct the order of file-list layer and empty-folder layer.

The UI indicating that the folder is empty is behind the file-list layer.
It used to be visible because the file-list has transparent background, but with
https://codereview.chromium.org/2554433002, file-list got background color and
the UI turned invisible.
We should correct the order of layers instead of reverting the background color
of file list, as the background color of file list is necessary to make use of
native overlay scrollbar.
