[tor-commits] [bridgedb/master] Only add a bridge to the splitter if it is new.

[isis at torproject.org]

commit 92eb6fe9e7d4e1e7cbb72687b9f41f5f827fa182
Author: Matthew Finkel <Matthew.Finkel at gmail.com>
Date:   Tue Mar 4 03:59:41 2014 +0000

    Only add a bridge to the splitter if it is new.
    
    If it's not new then we want to overwrite the old instance.
    Unconditionally appending to to the splitter results in duplicate
    bridges.
    
    Closes #9264
