Why default err message is used instead of "attribute 'subject' cannot be null"?

I think it's not so good to place error message here. In some cases, such as lack of attribute source, we get an error message like this from reader.toEvent().
Caused by: com.fasterxml.jackson.databind.exc.MismatchedInputException: Missing mandatory source attribute
at [Source: (byte[])"{
"specversion": "1.0",
"type":"com.example.someevent",
"subject":"test_topic",
"datacontenttype":"text/plain",
"id": "A234-1234-1234",
"data": "aa"
}"; line: 8, column: 1]
It contains '\r\n' which cannot be used in the http status message and causes another exception in setStatusMessage.

As a result, the server cannot response to the sender.
Maybe it's better to response a json containing the error message, but I am still thinking about how to standardize the way the errors are described.
{
"reason" : "attribute 'subject' cannot be null"
}

@Fungx What is the error message returned to the sender when source or subject is missing after your modification in this PR?
