Function deltachat::ephemeral::start_ephemeral_timers

pub(crate) async fn start_ephemeral_timers(context: &Context) -> Result<()>

Start ephemeral timers for seen messages if they are not started yet.

It is possible that timers are not started due to a missing or failed MsgId.start_ephemeral_timer() call, either in the current or previous version of Delta Chat.

This function is supposed to be called in the background, e.g. from housekeeping task.
