e_service_gesture: do not raise a gesture without 1st finger event

e_service_gesture expects multi-touch events coming after 1st finger events.
There was the bug that a gesture started from 2nd finger event and
didn't end properly since 1st finger was consumed by e-mod screen reader.
This patch add prevention check if 1st finger did come or not.
