update command name to match class name

Description

This PR aims to fix a problem in the EventSourcingServiceProvider:54, where the clear command is typed differently from the command signature.

Fixed Error when running optimize:clear

Hmm I this fix should be the other way around: EventSourcingServiceProvider:54 should be updated, not the command signature. Otherwise it's a breaking change.

@sebastiandedeyne Sure, it makes sense. I've made the change.
