fix(dynamic-links): prevent crash when annotation is null

[edusperoni]

Apparently the options are always empty https://github.com/firebase/firebase-ios-sdk/blob/136e71f7aa438236421307a69c01789855515464/FirebaseDynamicLinks/Sources/FIRDynamicLinks.m#L544

@triniwiz there is any chance to get a release with this fix today? we are blocked and not able to publish apps on iOS because of this

I'm facing a iOS device crash when I include the dynamic-links plugin, however this happens only the first time when the App is installed, subsequent re-opens don't cause a problem.

During compilation, I noticed the below error:

Users/vijay/Projects/community/node_modules/@nativescript/firebase-dynamic-links/platforms/ios/src/TNSFirebaseDynamicLinksAppDelegate.swift:30:146: warning: expression implicitly coerced from 'Any?' to 'Any'

dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromUniversalLink: url)

Environment setup:

• Mac OS : 12.4
• iPhone OS : 15.5
• NativeScript : 8.2.3

I'm sure the crash is due to the plugin because I've experimented several times by including and excluding the package from the build.

Requesting some assistance on this. Btw, it works fine on Android.
