Language Client sendRequest parameters

LanguageClient.sendRequest does not seem able to send a request without a params field, making it impossible to call some certain kinds of requests.

I’m trying to send a request that has no parameters, but receive errors like this in response:

Deno Language Server[14:35:10.679000] Received JSON-RPC response: number(6) deno/task
  "jsonrpc" : "2.0",
  "error" : {
    "message" : "Unexpected params: null",
    "code" : -32602
  "id" : 6

And it’s true, even though I don’t specify any parameters, the request itself is being sent with null as the parameters:

Deno Language Server[14:35:10.679000] Sending JSON-RPC request: number(6) deno/task
  "jsonrpc" : "2.0",
  "id" : 6,
  "method" : "deno\/task",
  "params" : null

There doesn’t seem to be any way for me to get Nova to omit the params field entirely, which is allowed by the LSP spec: Specification
