Unrecognized field: `urgent_mention_count`

[euronymous]

Sorry, IDK how to add a new field to a model, to maintain backward compatibility.

Caused by: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "urgent_mention_count" (class net.bis5.mattermost.model.ChannelUnread), not marked as ignorable (7 known properties: "msg_count_root", "msg_count", "mention_count_root", "notify_props", "team_id", "channel_id", "mention_count"])
