* Ensure we dont raise exception if e.cause does not contain a message
* Ensure we handle case where e.path may be empty
* Refactor existing tests to conform to new format
Created a new schema that accepts request parameters for the
get_notifications v2 route.
Using that to validate now instead of the marshmallow validation.
Also changed the way formatted error messages are returned because
the previous way was cutting off our failing `enum` messages.
This is the schema that individual notifications will conform to
when they are returned from this API.
JSON logic enforces that the right keys are set depending on the
`"type"`. (eg a schema with `"type": "sms"` must have a
`"phone_number"` value and it cannot have an `"email_address"`)
Update the format_checkers to raise the specific exception that why the validator can handle multiple messages.
Which led to a refactor of build_error_message.
Start building up the validators required for post notificaiton.
The app/v2/errors.py is a rough sketch, will be passed a code, the error can look up the message and link for the error message.
