[user model] Fix notification click listener not firing on cold start

[nan-li]

Description

One Line Summary

Fix iOS notifications clicked event not firing when clicking a notification to open the app from a cold start.

Details

Motivation

Fixes iOS bug where notification click listener is set but not firing when clicking the notification from a cold start.

Scope

In the iOS bridge, the setLaunchOptions has been updated to call initialize:nil withLaunchOptions:launchOptions so that the SDK can be initialized in order to get the cold start notification click event. This will result in the iOS SDK reading the appId from cache when nil is passed.

Testing

Manual testing

Tested the following scenarios on an iPhone 13 Pro with iOS 16.6:

1. Add click listener on app start. Kill app and and click notification to open from cold start. Alert is shown via visual logging.
2. Click on notification from cold start, app opens, then add the click listener from a button. Click event for previously-clicked notification successfully fires.
