[iOS]Missing markers after removeAnnotations/addAnnotations is called

[andrewstay]

**Platform:**iOS
Mapbox SDK version: ios-v3.4.0-beta.4

Steps to trigger behavior

1. Create an instance of MGLMapView
2. Add annotations with random data
3. Provide view for the created annotations via
   -[MGLMapViewDelegate mapView:viewForAnnotation:]
4. Observe views are correctly instantiated and displayed in the map.
5. Remove existing annotations as following:
   [self.mapView removeAnnotations:self.mapView.annotations];
6. Instantiate new random annotations and set them up into the instance of the map view
   [self.mapView addAnnotations:annotations];

Expected behavior

All newly added annotations which fit the visible coordinates should be displayed.

Actual behavior

The annotations which are located close the the edge of the visible bounds are not displayed. Only few annotations are visible in the map.

Please review the video and the test application attached.

Also, thanks so much @andrewstay for the detailed description and attaching the repro app. That was very helpful! Beta 5 is available so please test again with that version.
