    Bug Description: userpasswd not replicating

    Fix Description: The problem is happening because we are replicating
    the unhashed#user#password attribute.  The consumer gets this sequence:
    
    delete: unhashed#user#password
    -
    add: unhashed#user#password
    unhashed#user#password: value
    
    The code in entry_wsi_apply_mod attempts to apply the delete, but since the
    attribute does not exist, it returns LDAP_NO_SUCH_ATTRIBUTE and the entire
    modify operation is rejected.  The server removes unhashed#user#password before
    doing database operations in the non-replicated case, but in the replicated
    case it is assumed we can just apply the operations as they are given by the
    supplier.  pw_change is never set in the replicated case, so the consumer
    never removes unhashed#user#password.  The solution is to just remove
    unhashed#user#password even if pw_change is not set.  If the attribute is
    not in the mods list, remove_mod is a no-op.
