    file: Fix reference leak
    
    We are missing a "nautilus_file_unref(parent);" statement is missing in
    the get_filesystem_remote() method, leaking a reference.
    
    This was detected by a failing self-check test in a branch:
    https://gitlab.gnome.org/GNOME/nautilus/-/jobs/720894
    
    Let's fix this with autocleanup.
    
    For consistency, change the neighboor get_filesystem_type() to use
    autocleanup too, instead of the explicit nautilus_file_unref().
    
    
    (cherry picked from commit 9ef5d8344bf8355eceff291d9cd7029b532b9933)
