[Bug] koa-context-validator is throwing an error rather than returning a 400 response

[barthofu]

What happened?

Not quite a bug but more of an unexpected behavior.
The koa-context-validator is throwing an error on the server when the request's query/body is not validated.
It would be better to return it to the client in the form of a 400 (bad argument) response error, with the Joi's error description as the response message.

But the middleware ecosystem of Koya is quite poor and rarely used.
I propose to either:

• Create our own middleware (and possibly publish it on npm)
• Switch to another web server (such as @node-decorators/express)
