sectionsd: more optimization of addEvent() (thanks Gaucho316)

Browse Source 
This saves an SIevent constructor by temporarily modifying the
already created event. Also slightly reduces code size.
Performance impact: ~6.5% when reading 25000 events from disk on
coolstream, almost not noticeable (< 1%) on tripledragon.
The idea came from Gaucho316.
