Discard LSP publishDiagnostic when LS is not initialized (#3403)
This is invalid according to the [LSP spec]:
> In addition the server is not allowed to send any requests
> or notifications to the client until it has responded with an
> InitializeResult, with the exception that during the initialize
> request the server is allowed to send the notifications
> window/showMessage, window/logMessage and telemetry/event as well
> as the window/showMessageRequest request to the client.
So we should discard the message when the language server is not
yet initialized. This can happen if the server sends
textDocument/publishDiagnostics before responding to the initialize
request. clojure-lsp appears to exhibit this behavior in the wild.
[LSP Spec]: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize
