Fix layout constraints warnings.

Multiple broken layout constraints warnings are emitted during device rotation, when presenting NavigationViewController etc.

For example:

2020-09-16 15:42:16.866985-0700 Example[33378:535029] [LayoutConstraints] Unable to simultaneously satisfy constraints.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it. 
(
    "<NSLayoutConstraint:0x60000025bd40 H:|-(8)-[UIImageView:0x7f92dc821120]   (active, names: '|':MapboxNavigation.NavigationMapView:0x7f92da68d000 )>",
    "<NSLayoutConstraint:0x6000002597c0 H:|-(0)-[MapboxNavigation.NavigationMapView:0x7f92da68d000]   (active, names: '|':MapboxNavigation.NavigationView:0x7f92dc81c130 )>",
    "<NSLayoutConstraint:0x600000259cc0 UIImageView:0x7f92dc821120.leading == MapboxNavigation.NavigationView:0x7f92dc81c130.leading + 10   (active)>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x60000025bd40 H:|-(8)-[UIImageView:0x7f92dc821120]   (active, names: '|':MapboxNavigation.NavigationMapView:0x7f92da68d000 )>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

In scope of this ticket such broken constrains should be detected, UI components constrained correctly and warnings fixed.

Reproduce the warnings during device rotation while presenting NavigationViewController and inspect the listed active constraints, especially those involving NavigationMapView and UIImageView. Trace each constraint to the UI component that creates it, then verify that rotation and presentation complete without broken-constraint warnings.
