SIP.js: this.options.uri.clone is not a function in new API

Describe the bug I am trying to use the new API in SIP.js 0.15.3 and am unable to get a URI.

Logs Following the docs when I try to use the method userAgent.makeTargetURI(“someuser@somesubdomain.onsip.com”) results in the following error: this.options.uri.clone is not a function. (in 'this.options.uri.clone()', 'this.options.uri.clone' is undefined)

And attempting to simply give a URI in the form of a string directly will result in the following error: ruri.clone is not a function. (In 'ruri.clone()','ruri.clone' is undefined) I have used the exact string before with the previous API so I know it is valid.

To Reproduce (if possible) Follow the docs on new API in react native.

Expected behavior String to be parsed into a valid URI.
