fix(chat): Resend auth token on server restart

[nkomonen-amazon]

Problem:

When the server restarted due to a crash, the auth token was not sent again. This caused users to run in to the state where if it crashed and restarted, when they sent a subsequent chat message they'd get stuck with the server asking the user to Authenticate.

Note that server restart is triggered automatically by the LanguageClient, I think.

Solution:

Detect when the server is restarted and manually resend the bearer token again.

Note, this solution needs to be revisited since there may be other initialization logic that needs to run on server restart, aside from just the bearer token.

Repro Steps:

1. Ensure you do not have a workspace open, you can open a new vscode window at the top left File > New Window
2. Make a random folder in your home directory
3. Make a couple typescript files in that folder
4. Send the prompt: list all files in {folder}
5. Accept the permissions
6. Click the toggle drop down from the response, and click the link to the path (this is just to force a crash + restart)
7. Verify the server crashed in the logs, look for the message Connection to server got closed. Server will restart.
8. ASSUMING this fix worked, the server will restart automatically and you can continue using chat. Before this fix any subsequent messages would ask the user to Authenticate again
