fix(ios): link menu action Cupertino modal popup now does NOT use root nav

[Zambrella]

Description

This is to fix a bug where when using nested navigators the modal popup wouldn't pop (instead, the underlying pages would). This also brings the behaviour into parity with the Android/Material equivalent.

Merged but there's no guarantee the fix will remain since we don't have a related test for the bug fix.

Thanks for your contributions.
