[BUG] device.register() get stuck when the WebSocket fails to connect

[kamalbennani]

• I have verified that the issue occurs with the latest twilio.js release and is not marked as a known issue in the CHANGELOG.md.
• I reviewed the Common Issues and open GitHub issues and verified that this report represents a potentially new issue.
• I verified that the Quickstart application works in my environment.
• I am not sharing any Personally Identifiable Information (PII)
  or sensitive account information (API keys, credentials, etc.) when reporting this issue.

Code to reproduce the issue:

While attempting to initialize a Twilio Device with an expired token results in the failure of executing subsequent code following the invocation of await device.register().
This occurs due to the Twilio WebSocket being closed caused by the token expiration, preventing the register() promise to be resolve/reject.

(async () => {
  try {
    const device = new Device('AnyExpiredToken');
    await device.register()
  } finally {
    console.log('log never reached');
  }
})()

Expected behavior:

The .register() function should throw an error indicating that the device has failed to register.

Actual behavior:

register() promise never resolves.

Software versions:

• Browser(s): 120.0.6099.109
• Operating System: MacOS 13.5.2 (22G91)
• twilio.js: 2.8.0
• Third-party libraries (e.g., Angular, React, etc.): React
