Describe the bug

When disposing a call agent, a TypeError is thrown: TypeError: Cannot read properties of undefined (reading 'offStateChanged')

To Reproduce

Steps to reproduce the behavior:

const callClient = new CallClient();
const credential = ... ; // create a token credential

const teamsCallAgent = await callClient.createTeamsCallAgent(credential);

teamsCallAgent.dispose();  // TypeError

Expected behavior

Disposing call agent should not cause a TypeError.

Screenshots

N/A

Additional context

Stack trace:

TypeError: Cannot read properties of undefined (reading 'offStateChanged')
    at CallStack.offTrouterStateChanged (sdk.bundle.js:196:809580)
    at TeamsCallAgentImpl.offTrouterStateChanged (sdk.bundle.js:196:591843)
    at TeamsCallAgentImpl.<anonymous> (sdk.bundle.js:196:859643)

This does not happen in previous version of the SDK.

I would just like to add that this happens with the regular CallAgent created from the createCallAgent method call as well.

Seems to be fixed in 1.15.2-beta.1
