The specified child already has a parent.

Hi,

I think there is a bug:

• react-native: 0.56
• react-native-maps: 0.22.0
• react-native-maps-super-cluster: 1.5.0

First I got this issue react-native-maps/react-native-maps#2507

Then I fixed it by the PR: react-native-maps/react-native-maps#2555

But I got the following error:

The specified child already has a parent. You must call removeView() on the child's parent first.

Hi.
I found out this problem when run the app on Android, the iOS project works well.
In my case solution was changing key from object_id to indexer.

<MapView ... >
{
_.map(clusterData, (item, index) => (
   <Marker
                coordinate={{longitude:  item.coordinates[0], latitude: item.coordinates[1]}}
                onPress={() => this._markerPresed(item)}
               key={index}
            />
) );
}
</MapView>

There was key={item.id}
I don't know why, but key={index} works well.
