[eog] Make sure to only reuse an empty window if it is done initializing

[Felix Riemann <friemann src gnome org>]

commit 92c37ff6b34a2866ba2d03be7f6e1e973c707419
Author: Felix Riemann <friemann gnome org>
Date:   Mon Jun 4 21:55:29 2012 +0200

    Make sure to only reuse an empty window if it is done initializing
    
    This avoids a race condition when opening images through multiple instances.
    The second instance could then override the already loading (hidden)
    window's image resulting in only one image window showing.
