iOS issue with notification hubs

[rlennoxmemoro]

The Xamarin.Azure.NotificationHubs.iOS package throws an error in iOS:

2023-03-02 15:55:24.309 *** -[NSCalendar isDate:equalToDate:toUnitGranularity:]: date1 cannot be nil
Future exception.
A few of these errors are going to be reported with this complaint, then further violations will simply be ignored.
Here is the backtrace where this occurred this time (some frames may be missing due to compiler optimizations):

Another package from Microsoft had the same issue and it was fixed there...unfortunately that isn't the one we are using due to other issues it has.

See this bug in the other repo:
Azure/azure-notificationhubs-ios#112
