[libchamplain] Properly finish the pending goto animation during a dispose.

[Pierre-Luc Beaudoin <plbeaudoin src gnome org>]

commit 853e16ab96a6dc7f721400ad7a86ed2bfa402995

    Properly finish the pending goto animation during a dispose.
    
    If the view is closed while an animation is pending the program will crash with
    the error *** glibc detected *** perl: double free or corruption (!prev): 0x09a68160 ***
    See bug: http://bugzilla.gnome.org/show_bug.cgi?id=585776
    
    This patch seems to fix the problem.
