lsp: opening multiple-files in a short period causes a deadlock

[kitsonk]

When the lsp receives several textDocument/didOpen messages in quick succession it can cause a dead-lock, as the lsp is querying the client for configuration information. This can occur if a user is doing a find/replace across multiple files. This only affects Deno 1.10.0.

@ry this diff works the bug but disables the workspace folder config:
