A result of 'false' is converted to '{}'

[0xJMR]

First of all, I must thank you for this project. As of this writing, I struggled to find a JSON-RPC implementation which is transport-agnostic, works out of the box with TypeScript, and makes use of ECMAScript 6 Proxy objects in order to abstract from the actual communication.

Overall, I did not encounter any problems except for the following one. Let us assume that you have a remote object with a method isReadable which returns true if a document is readable and false otherwise. Furthermore, let us assume that the method is executed on a document which is not readable. The remote call of this method would therefore return false and the expected result for the local method call would therefore also be false. However, instead one receives {} as result.

The problem lies within the lines 261 and 267 of noice-json-rpc.ts. The shortcut result || {} used to give undefined results a default value will also evaluate to {} for false as result and this might be unwanted behavior. Replacing this part with something like result === undefined ? {} : result should fix this issue.

Thanks for the catch. Will look into it.
