[nautilus] undo: remove some URI->GFile roundtrips in the trash undo operations

[Cosimo Cecchi <cosimoc src gnome org>]

commit 9736b263c7830dad6c9de6b42f131395201b993b
Author: Cosimo Cecchi <cosimoc gnome org>
Date:   Mon Jan 23 13:17:00 2012 -0500

    undo: remove some URI->GFile roundtrips in the trash undo operations
    
    We can just store GFiles directly in the hash table and use
    g_file_hash() and g_file_equal() instead of parsing the URIs ourselves.
