    filediff: Make conflict resolution prompt use correct path (bgo#756148)
    
    We were incorrectly using the loaded file, but Meld's conflict
    resolution code always sets a merge-output file. Until recently these
    always happened to be the same, but the new git merge changes made
    this no longer the case.
