added missing iOS constructor in ListViewRenderer

[narciszait]

Description of Change

Added a missing constructor in ListViewRenderer

Issues Resolved

Could not find it. But I saw it in the app crash logs:

ObjCRuntime.RuntimeException

Failed to marshal the Objective-C object 0x28382b600 (type: Xamarin_Forms_Platform_iOS_ListViewRenderer_ListViewDataSource). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'Xamarin.Forms.Platform.iOS.ListViewRenderer+ListViewDataSource' does not have a constructor that takes one IntPtr argument).

API Changes

Added:

• public ListViewRenderer(IntPtr handle)

Platforms Affected

• iOS

Behavioral/Visual Changes

By having that missing constructor, we avoid that exception

Testing Procedure

I saw it in our crash logs.
Don't know necessarily how to reproduce it.

PR Checklist

• Targets the correct branch
• Tests are passing (or failures are unrelated)

Could you share a more detailed logs to try to know when this happens?. Thanks for the PR and the feedback.

Not sure it will fix the issue but I guess it doesn't hurt as well :)
