Artefacts offline mode

[Comanga]

Platform: iOS 10
Mapbox SDK version: v3.6.0

Steps to trigger behavior

1. Download Mapbox's sample project: https://github.com/mapbox/ios-sdk-examples
2. Go to OfflinePackExample_Swift
3. Fully download the map with an internet connection
4. Kill the application
5. Go back in airplane mode 6 ~ 24 hours later (that's where the bug is tricky to reproduce but when it happens the map will always be buggy)

Expected behavior

No artefacts (version 3.5.4 works normal)

Actual behavior

I don't know if the problem is related to this issue #9211 but it occurs even in Mapbox's examples...

Here is a video to demonstrate the glitch: https://youtu.be/i0tdzvjYEig (don't pay attention to the wifi logo, quicktime adds it).

I have the same issue using 3.6.0 with objective c.
Any progress ?
