[Bug] No error when try push outside NavigationPage

[pictos]

Description

Steps to Reproduce

1. Create a simple app, and make sure that App.MainPage is any ContentPage
2. Create a button and implement a clicked event that does Navigation.PushAsync()
3. Nothing happens

Expected Behavior

1. See an exception or log that tells me that I need to have a NavigationPage as the root page.
2. When App.MainPage has a NavigationPage as the root page I want the breakpoint, inside click event handler, triggers (as you can see in the video that doesn't happen).

Actual Behavior

Nothing happens

This is still an issue. The bug is that we should throw an exception if you aren't wrapped with a navigationpage.
