Set control type doesnt work for element not on the screen

Set control type method doesn't work for controls that has been created in C# and hasn't been added to the page yet.

For example - 
```csharp
StackLayout test = new StackLayout();
test.Children.Add(new Label { Text = "Dynamic test" });

_accessibilityService.SetControlType(test, ControlType.Button);

TestContainer.Children.Add(test);
```

Not sure how to work around that.
