[PATCH b4 27/27] review: close the tracking database when archiving fails

Same thing the auto-mark block had a few patches ago: the connection is
closed in the last statement of the try, so a failing update_series_status()
skips the close and leaks it. The tracking UI archives from a process that
stays around for the rest of the session.

Close it in a finally instead.
