Crash when converting screencoordinate as part of moveBy

[tobrun]

we use Transform::moveBy for scrolling and fling gestures. There are cases as reported by customers that sometimes NaN value are produced for the latitude value:

java.lang.Error: latitude must not be NaN	
at com.mapbox.mapboxsdk.maps.NativeMapView.nativeMoveBy(NativeMapView.java)
at com.mapbox.mapboxsdk.maps.NativeMapView.moveBy(NativeMapView.java:242)
at com.mapbox.mapboxsdk.maps.Transform.moveBy(Transform.java:313)
at com.mapbox.mapboxsdk.maps.MapGestureDetector$MoveGestureListener.onMove(MapGestureDetector.java:494)

This happens as part of screenCoordinateToLatLng within Transform::moveBy.

Capturing from @pozdnyakov in an upstream ticket:

map transform API is not exception-free. Could this exception be caught and handled on platform side?

This PR addresses above comment by wrapping nativeMoveBy and logging the occurrence.
