Provider method that does not return anything results in invalid provider response RPC

[kpears201]

Author a provider class like:

class MyProvider {
   function action(actionParams) {
       console.log(actionParams)
   }
}

When action method is called and returns it generates rpc method like:

{
    "jsonrpc": "2.0",
    "method": "MyProvider.actionResponse",
    "params": {
        "correlationId": "abcdef-123-1111-111-1234234234"
    }
}

It is missing result which is a required field in the generated specification for provider responses.

If changed to:

class MyProvider {
   function action(actionParams) {
       console.log(actionParams)
       return null
   }
}

It should work as the result field gets set to null.

The Firebolt SDK should allow a provider method with no return. When result is undefined, set to null.
