[nautilus] files-view: Say "Trash is Empty" only in trash:///

[António Fernandes <antoniof src gnome org>]

commit 2a741d961750d3785cc5bf65db1775f52cae2285
Author: Abdul Rauf <abdulraufmujahid gmail com>

    files-view: Say "Trash is Empty" only in trash:///
    
    Empty trash widget is displaying for empty folder inside trash
    instead of Empty folder widget.
    
    `eel_uri_is_trash` only checks whether the URI starts with "trash:",
    that's why it also returns true for empty folders inside trash.
    
    Create `eel_uri_is_trash_root` to distinguish trash root (trash:///)
    from empty folder inside trash (trash:///emptyfolder)
    
    Closes https://gitlab.gnome.org/GNOME/nautilus/issues/1367
