fix(events): remove event db writes production

This commit removes writes to the db table until further notice.  This
is due to the remark that:
 1) massive numbers of events are being written
 2) events do not scale over multiple cores

This feature will be re-introduced when these are addressed and events
are needed to power client interactions.
