    [gnc-sx-instance-model] free some GHashTable keys & Values

commit 7c2a24951106c19f562efc745ed5c8d605cd5d53

    [gnc-sx-instance-model.c] refactor Scrub function
    
    This scrubbing function calls xaccTransRollbackEdit which is
    leaky. Instead of trying to fix xaccTransRollbackEdit which requires
    superhuman skills, it's easiest to track the changes separately in a
    GList, and use xaccTransBeginEdit/xaccTransCommitEdit only if
    necessary.
