Add meetingKeepEvents to the creation data to fix events

As per bigbluebutton/bigbluebutton#11681 and https://github.com/bigbluebutton/bigbluebutton.github.io/pull/239/files it seems that this new option was added to let the client control whether or not the data should be stored. The data needs to be stored if meeting stats are required so it can be sent back from the BBB server
