MSFNavigationBar does not update the title on the same instance unless titleView is reset.

MSFNavigationBar does not update the title on the same instance unless titleView is reset.
NavigationBar.Swift :: updateSubtitleView, it checks for navigationItem.titleView == nil and returns without setting navigationItem.titleView = customTitleView.

So without setting viewController.navigationItem.titleView to nil, the following code will not update the navbar title on the same instance of viewController if it was run once before.

viewController.title = "My Custom Title"
navigationController?.pushViewController(viewController, animated: true)

Please look into fixing this. If this is there for a reason for this behaviuor, please expose an API that allows to set navbar title without having set viewController.navigationItem.titleView = nil

Products/applications affected: (if applicable)

Start in NavigationBar.Swift, at updateSubtitleView, and reproduce the issue by reusing the same view controller with different titles. The work is done when the navigation bar title updates on the same instance without manually resetting navigationItem.titleView.
