Resolve AddTxTracker Function Bug in Worker Module

[Psykepro]

Overview:

A bug has been identified in the Worker's AddTxTracker function where a new AddrQueue is created for an address, just after its transactions have expired, but before the pending transactions for the same address are stored. As a result, the new AddrQueue is incorrectly initiated using oldStateRoot, old Nonce, and Balance. This bug disrupts the sequence of transactions and leads to potential data inconsistency issues and makes the sequencer to get stuck.

Recommended Changes:

1. Modify AddTxTracker Function:
   • Adjust the AddTxTracker function in the Worker module to wait for the pending transactions to be completely stored before initiating a new AddrQueue for an address. This can be achieved by checking the status of pending transactions and delaying the AddrQueue creation until all transactions are confirmed to be stored.

Objective:

The proposed changes aim to address the identified bug in the Worker's AddTxTracker function. By modifying the function to wait for pending transactions to be stored before initiating a new AddrQueue, we ensure data consistency and prevent potential errors caused by this bug.
