[CAL-3116] `bookingSuccessful` event is emitted even when the user clicks on `Cancel`, `Nevermind` etc...

[baptisteArno]

Issue Summary

When embedding a cal.com widget, the bookingSuccessful event is emitted even when the user clicks on Cancel, Nevermind etc...

I'd expect it to only be emitted whenever an event is successfully booked.

Steps to Reproduce

1. Embed a widget
2. Subscribe a callback to bookingSuccessful event
3. Book an event, then click on Cancel, then Nevermind
