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
