MGLAnnotationView's annotation property is nil -> crash

[RomainQuidet]

Platform: iOS 10
Mapbox SDK version: 3.5.2

We can't reproduce this problem on our own, but we've got some crashes from our users.
It states that the AnnotationView's annotation property is nil. We do not touch this property in our app, so the bug lies in the SDK.

This sounds like #8755 that should have been fixed by #9025 that was released in https://github.com/mapbox/mapbox-gl-native/releases/tag/ios-v3.6.0. Since you say above you are using Mapbox iOS Maps SDK v3.5.2, can you please update to the latest version that is currently v3.6.4

Hi,
We've updated to 3.6.4. I'll see if it solves the issue !
