OfflineManager.ListOfflineRegionsCallback doesn't work

[rakuishi]

Platform: Android
Mapbox SDK version: 5.2.0-beta.3

I made a sample project which can reproduce a below bug.
https://github.com/rakuishi/mapbox-gl-native-issue

I think OfflineManager depends on MapView's lifecycle.
Because, after removing mapView.onStop(), callback works fine.

Steps to trigger behavior

1. Launch MainActivity which it has a MapView.
2. Launch Main2Activity from MainActivity.
3. Then, call OfflineManager.getInstance(context).listOfflineRegions() by a touch event, but it's callback(OfflineManager.ListOfflineRegionsCallback) doesn't work.

Expected behavior

• OfflineManager.getInstance(context).listOfflineRegions() works correctly.

Actual behavior

• OfflineManager.getInstance(context).listOfflineRegions() doesn't work.

Additional Information.

Callback works fine, when I put FileSource.getInstance().activate() and FileSource.getInstance().deactivate()on MainActivity2's onStart() and onStop.

@rakuishi thank you for the write up, we were indeed missing a activate/deactivate call as part of OfflineManager#listOfflineRegions().
