Compile errors on TextDocumentSaveReason and MessageType.

[aeschli]

After migrating to ^3.0.2-beta.5 I get the following compile errors in vscode. Any idea?

[19:33:49] Error: /home/aeschli/workspaces/vscode/extensions/html/server/src/modes/javascriptMode.ts(67,11): Type '{ range: Range; severity: number; message: string; }[]' is not assignable to type 'Diagnostic[]'.

See microsoft/TypeScript#13594

I will more clearly type the enum constants since it helps work around this.

I will close the issue since there is nothing I can do right now. See the TS issue for details.

@aeschli fixed on the VS Code side by typing the fat arrow.
