before_send in Node.js not called by $identify

[Laruxo]

Bug description

In posthog-js before_send is called for all events including $identify and $groupidentify. Meanwhile, in posthog-node, it is only called for capture* functions.

How to reproduce

1. Add before_send(event) { console.log(event); return event } handler on the server
2. Call postHog.identify(...)
3. Nothing is logged to the console
