Request forwarding callback should be called only if set since it is an
optional parameter. In GetRangeHash forwarder is never set.
Call `forwarder` function only if it is non-nil. Remove no longer needed
`hashOnly` option.

In current implementation `Object.GetRangeHash` RPC handler forwards range
requests for payload data. Missing request forwarder of the original request
caused NPE during execution.
Do not call request forwarder if payload range hash is requested.
