Fix how Location selector is presented.

[mtnbarreto]

According to calendar app, location selector is presented from bottom (not as push view controller).
We can provide such configuration but the default behavior should mimic calendar app.

@mtnbarreto, I need some assistance with this and perhaps you can direct me towards any docs or examples?
The UISearchController is added to the UINavigationItem.searchController property but a modal presentation has no navigation controller as the PresentationMode uses the PresenterRow type alias that is a UIViewController.
Some custom row implementations add a navigation bar to the view controller xib in Interface Builder instead of using a navigation controller. This does work for a navigation bar with a title view, left and right buttons but the searchController property of its UINavigationItem appears to be ignored. I suspect the logic to use and render the contents of this property MAY be implemented by the navigation controller.
The fallback is to add a UISearchBar (instead of UISearchController) below the navigation bar in Interface Builder. However this is a last resort as it is old fashioned!
The ideal (and simplest) solution would be to present the selector view controller wrapped in a UINavigationController if possible.

@mtnbarreto, this is an approach I adopted that perhaps you can review?
