Test Project

## Description

When using a custom renderer in iOS project for a ListView, as in the Forms WorkingWithListViewNative sample, the ListView does not scroll unless you override GetDesiredSize. It is overridden in the sample, but it seems it should not be needed.

Test project is simply this project, https://github.com/xamarin/xamarin-forms-samples/tree/master/WorkingWithListviewNative, with the GetDesiredSize override commented out. 

## Steps to reproduce

1. Open the attached sample, restore packages and set the iOS project as the start up project.

2. Launch iOS project to device/simulator

3. Select tab 2 "B Native Native"

4. Scroll ListView

Expected result: ListView will scroll.

Actual result. ListView does not scroll

## Note

Tested using Forms 1.4.4
