match() should throw if no matching validator is found

[codeclown]

As per discussion in https://github.com/Hilzu/express-openapi-validate/pull/63...

• similarly to validate(), match() should throw an exception if the request doesn't match any spec in the OpenAPI Schema
• and this behaviour should be toggleable via an option, e.g. match({ allowNoMatch: true })

This is a breaking change compared to current behaviour.
