createConfiguration could use the path in the sync url

Goals

When using createConfiguration to create a configuration that syncs to something else than the /default Realm it would be nice if the user had a way to specify the path of the Realm on the server.

Expected Results

Either the config.path could be appended to the server URL or perhaps a second string argument to the method.

Actual Results

Calling createConfiguration on a user always returns a configuration object with the /default path.

Steps to Reproduce

1. Authenticate a user
2. Call user.createConfiguration({ path: "whatever" }), log the result and observe that it has /default as the realm path of the sync.url.

Version of Realm and Tooling

• Realm JS SDK Version: 2.14.2
• Node or React Native: Node
• Client OS & Version: N/A
• Which debugger for React Native: N/A

I think that would be very weird API as you’ll have two ways of specifying the same thing. I would rather handle relative urls in the sync object:

user.createConfiguration({
  sync: {
    url: "/whatever"
  }
});

We can easily detect that and concatenate with the user url.

I just had a need for this again today 😃 Glad to see it’s in active progress.
