Bug Sequential de-queuing

[cdriouech]

Problem

• (X) bug report => please search github for a similar issue or PR and test Modbus problems with the modbus-serial package before submitting
• ( ) unexpected behavior => please visit the Wiki before

Current behavior
Blocking serial messages on Timeout and sequential queue.

Expected behavior
It should not block the queue and every response should release with error if blocked.

Minimal reproduction of the problem with instructions

1. serial device request per unit-id with connection and without
2. send requests to them id by id
3. timeout or reconnect will appear
4. "sequential dequeue command not possible" error

Your Environment

Please tell us about your environment:

• ( ) I am using just the Node-RED package and got modbus-serial package installed with it
• ( ) I have installed modbus-serial package global from source (using git clone)
• ( ) I have installed modbus-serial as a global package (using npm i -g)

Yes, modbus-serial is the name but it does all, TCP and Serial.
The node-modbus package is just for the Modbus Server node.
