Bug description

Within one of the latest builds of EssentialsX, the PaperChatListenerProvider has been introduced. It's handler onHighest causes an obvious NullPointerException, as follows: wrapping here creates a PaperChatEvent, whose format is suspiciously called fakeFormat and remains null, if not explicitly set - said format is not inherited from the wrapped instance. When passing this null-value to the serializer here, it causes the internal NullPointerException, as this parameter is expected to be non-null.

Steps to reproduce

1. Download and install the latest available builds of EssentialsX onto a Paper server
2. Send any chat-message
3. Notice the corresponding exception printed to the console

Expected behaviour

No exception caused, because there's either a null-check introduced, or the format is simply inherited.

Actual behaviour

Console is spammed if players chat actively.

Additional Information

No response

Personally I couldn't reproduce this, and the chat format is actually set in PaperChatHandler during the handleChatFormat call. I made a change in #6067 that switches the type of map we use to store the in-transit events. Go ahead and try the latest build and let me know if you're still getting the error.
