Polish query accepting (microsoft#183995)

We shouldn't send the same request to Copilot if the query hasn't changed. So if the query is the same, we short circut.

Fixes microsoft/vscode-internalbacklog#4286

Also, when we open in chat, we should use the last accepted query, not what's in the input box.

Fixes microsoft/vscode-internalbacklog#4280
