[nautilus] Use window_get_extra_slot instead of get_directory_view_of_next_pane

[Alexander Larsson <alexl src gnome org>]

commit 1545e04eaf41068c3add34792815b2df84b7fd5d

    Use window_get_extra_slot instead of get_directory_view_of_next_pane
    
    We want to remove get_directory_view_of_next_pane as the main code
    should not reference FMDirectoryView.
