Returns a standardised 500 error.

To be used in the event of a catastrophic failure, this method creates
all new objects, ignoring dependency injection and returns in JSON.

This will be problematic for users expecting a response in a format
other than JSON and should only be called if the format they are
actually expecting can not be provided when using
Response::prepareResponse.
