Set tchain earliest/latest on any removal

Alarm handlers can put themselves back on the tchain during their handler.
The logic for that involves the earliest/latest times.  Those times should
change since the old awaiter (which is running) was yanked off.

I didn't have any actual problems with this, but it popped up as a
potential issue.
