+/**
+ * What this is aimed to test:
+ *
+ * Expiration relies on an interval, that is user-preffable setting
+ * "places.history.expiration.interval_seconds".
+ * On pref change it will stop current interval timer and fire a new one,
+ * that will obey the new value.
+ * If the pref is set to a number <= 0 we will use the default value.
