When we send a Kafka message to update or delete invite, in both cases we delete invite from the ES index as per logic here https://github.com/topcoder-platform/project-processor-es/blob/develop/src/services/ProcessorServiceProjectMemberInvite.js#L57-L63
At the moment if no invite has been found and removed handlers to update or delete still return success.
Instead of this, if no invite has been found and removed, the handlers should throw an error:
Invite with email "{email}" and userId "{userId}" is not found and not removed.
Create a 2 unit tests that would test this case, one for update handler and one for delete handler.
