Fix TextDocument synchronization for LSP3

N. Taylor Mullen · web-flow · commit 90c06d043a0b · 2020-01-13T10:36:02.000-08:00
- For LSP3 clients the TextDocumentSynchronization kind is always set to none without this. For the VS LSP client this results in language servers never getting any text document synchronization events.
