Fix establishing connection with users

The existing erroneous connections can be found by running:

(fun() ->
    T = automate_service_port_channel_user_to_bridge_connection_table, 
    R = lists:filtermap(fun(K) -> 
                 R = mnesia:dirty_read(T, K),
                 case R of
                     [V = {_, _, _, {user, {user, UserId}}, _, _, _}] -> {true, V};
                     _ -> false 
                 end
             end,
             mnesia:dirty_all_keys(T))
 end)().

And can be fixed with:

(fun() -> 
    T = automate_service_port_channel_user_to_bridge_connection_table,
    mnesia:transform_table(T, fun(R) ->
        case R of
            {A, B, C, {user, {user, UserId}}, D, E, F} -> {A,B,C,{user, UserId},D,E,F};
             X -> X
        end
      end,
      [id,bridge_id,owner,channel_id,name,creation_time])
 end)().
