Explore how to maintain database transactions in nested services

[darth-dodo]

Description

• If the commit parser service raises rollback, the parent services do not rollback the Event creation as the errors weren't bubbling up to the parent service level
• Currently I have implement raise_rollback_unless_valid but this does not work effectively with nested services
• This is required if we want to parse the entire response and create a list of all the errors before rendering to the client
• Rethink the usage of

raise_rollback_unless_valid

and

return false unless valid?

on the service (especially nested services) level
