@Representer(null) should not try to serialize data

Take following controller function:

It generates a Maximum call stack size exceeded:

This is because even though we set our representer to null, the handler returns a token entity (I like to return the token for testing purposes), we still call classToPlain in the representer middleware. We should do a null check on the representationType, and if it's null, return null as well.

Additionally, when the strictNullChecks flag in tsconfig is set to true, we have a type error

Ah, nevermind, I should use @OnUndefined() instead of @Representer(null)
