#6527)

## Problem:

When a user starts up VSC, hasn't opened Q chat yet, then highlights
text and does a right click option like "send to prompt" THEN the whole
prompt fails to make it to chat.

This is because there is a race condition between the message being sent
to the webview, and the webview completed loading and ready to recieve
messages.

## Solution:

In the appToMessage publisher, verify that the chat is ready to recieve
messages based on if the webview sent the chat ui ready message.
Otherwise wait until we get it, and then send the message.
