Remove member from cache when ban

[PyGaVS]

What are the changes?

Removing the member from the server cache :
marshaller.cache.remove(memberCacheKey)
And updating the server in the cache :
marshaller.cache.put(serverCacheKey, rawServer)

How to test the changes?

Replace that :

await Future.wait([
      marshaller.cache.put(serverCacheKey, rawServer),
      marshaller.cache.put(channelCacheKey, rawChannel)
    ]);

By that :

marshaller.cache.has(memberCacheKey).then((value) => print(value));
    await Future.wait([
      marshaller.cache.remove(memberCacheKey),
      marshaller.cache.put(serverCacheKey, rawServer),
    ]).then((value) => marshaller.cache.has(memberCacheKey).then((value) => print(value)));

It should log true at the beginning when the member is not removed from the cache and false and the end when the member is removed.
