If a status in a conversation view controller creates a work item to update the timestamp in 1 minute, but the view controller is deinit'd before that time elapses, the mastodonController instance will be nil, resulting in a crash. The DispatchWorkItems's are cancelled by the respective cell deinit methods. But if the work item has already begun, cancelling it has no effect, potentially leading to a crash in the conditions described above are true. Using a weak reference to self fixes this. Additionally, don't unnecessarily recreate the work items every time. They don't capture any local variables, only self, so nothing changes.
