End the TC session on terminal selection event actions

This regressed when introducing TC sessions in
I3c9ceea0863099fc4f0a5ce5e823c648ee9c4521
When the user triggers a terminal selection event such as "Copy",
we should immediately end the session instead of waiting for the
"Abandon" event (i.e. selection dismissed) to be included in the
logs. Terminal selection events implicitly dismiss a selection and
we'd rather distiguish between an actual "selection dismiss" from
one that happened because of a "terminal" selection event.

This cl also removes the "*" marker used to distinguish the new
logging from the old ones. The code for the old logging has already
been deleted so no more need for a marker.
