Disable saving the reason in kick messages

[BlackYps]

Describe the Feature

When kicking someone from a lobby, the kick message has a reason attached. At the moment the reason gets saved from the last time. This can lead to confusion when people don't bother to type in a new reason. It seems rather unlikely that you will kick somebody for the exact same reason as the last time you kicked somebody from a different lobby. Saving the message while in the same lobby is fine.

Expected Behavior

We should disable the saving of reasons between lobbies and rather provide no reason at all if no was given. If we need to attach a reason for technical reasons we should fall back to some default string along the lines of "".
