 * the same session, and stays quiet on failure: an offline launch should start
 * normally and try again next time, not block on a network request.
 *
 * Returns the seeded ids so a caller that already holds the config in memory
 * can adopt them. The desktop loads its config before restoring, and without
 * this it would keep an object whose `seededPlugins` is one launch stale and
 * overwrite the record on the next save.
