Extra icon on TabbedPage in iOS 10

This is due to a bug in iOS 10, more information available here:

If the "Title" property is changed on an item in a TabbedPage, it updates the Title property on the TabBarItem (see This causes an additional icon to display (see attachment). Since the Title property is changed during binding, this means you can't bind the ItemsSource for a TabbedPage without seeing this extra icon.

I can see it on my simulator and on a real device both running release versions of iOS 10, so it's not just a beta bug.

I have provided a minimal repro on the linked PR. The important thing seems to be changing out the collection that ItemsSource is bound to.
