Summary

When saving the file, editor is not triggering textDocument/didSave notification, resulting in absent diagnostics until file is reopened manually.

From LSP specs it's clear that event should be 'opted in', and server must define .save field in textDocumentSync property in capabilities

/**
* If present save notifications are sent to the server. If omitted the
* notification should not be sent.
*/
save?: boolean | SaveOptions;

Right now ALS defines capabilites as just TextDocumentSyncKind.Incremental, which does not imply opting in to save notifications.
