fix: non HTTP requests are undefined in built-in AuthGuard

[replio-it]

Hi all, nice to meet you and these project.

the AuthGuard also comes into operation when requests that are not HTTP arrive such as amqp (rabbit MQ).
In fact, there are modules such as @golevelup/nestjs-rabbitmq that provide a decorator that works in a similar way to the http core decorator provided by nest, and therefore subject to middleware.
The module's built-in AuthGuard does not detect the undefined returned by the extractRequest function, causing an exception just after reading request.cookies.

the workaround I found immediately is to use the decorator @Unprotected() thus entering the condition isUnprotected

The real solution instead could be to insert a simple condition whereby if request is undefined, the guard returns true (because it is out of its competence).

I am therefore sending you a pr with the solution I have undertaken, hoping that from your point of view it can be really decisive

Only a linting problem, should be no issue to merge.

Hi at all,

good to see someone else has same problems. We are using mqtt and also get the error around "request.cookies". The solutions helps us for the AuthGuard but we are getting similar problem in the RoleGuard. Should we insert the same condition in the RoleGuard? Will this be a correct solution?

I think RoleGuard shouldn't process anything at all without being handled by AuthGuard before, I'll do this change myself along with the check for request.cookies.
