fix(training): keep practice laps in training stats after Reset data

Resetting a running Open Practice deleted its results, the Timing view
recreated an empty result at once, and the next save rebuilt that
session's training laps from nothing - wiping every earlier lap from
the drivers' stats. Reset now syncs first and records resultsResetAt;
laps from before it are kept.
