Only consider SVGSMILElement::previous_interval_begin_ if is resolved

Since an unresolved SMILTime will always differ from a resolved
SMILTime, the |new_begin_time| condition could turn true at the end of
an interval, resulting in the firing of an additional 'beginEvent'.

Add a check for |previous_interval_begin_| being resolved to the
condition, and also make sure it is updated when we get a new interval.
