What is the current behavior?

On iOS by default the TabView resets the navigation in a single tab when the tab is re-selected. This breaks navigation as it's not handled by NS.

What is the new behavior?

This behavior is disabled.

Fixes NativeScript/nativescript-angular#1466

AFAIU, this is a problem only with Angular as the native navigation gets out of sync with the Angular navigation.
Is it possible to make a property disabling the re-select tab feature and use it for Angular?

[MartoYankov]

There are several points to be made here:

1. This actually breaks the Core framework too, but it's not that obvious. If you navigate several times and reselect the tab, it will reset the Frame to the root view controller and it's UI will work, but we haven't cleared the Frame history stack, so if you call goBack() it will break.
2. Making this a property and integrating it in Angular would make this more a feature than a patch. We should probably do this separately.
