Log the contact when Ctrl+Z opens the QTC window, ESM or not

Ctrl+Z logged the contact by calling the Enter handler. With ESM switched
on, Enter sends the next message of the contact instead of logging it, so
the QTC window opened over an unlogged contact and the traffic went into the
log in front of the contact it belongs to.

It now calls LogContact, which is what N1MM calls at the same point. A
station already worked is logged again as a dupe, worth no points, which is
what the WAE rules expect: the second contact does not count but the traffic
does.
