Allow middlewares to be auto bound

[rtomchinsky]

Description

This PR allows the middleware to be resolved when autoBindInjectables is true, by checking the container options and getting the middleware instead of checking if it is bound.

Motivation and Context

When creating the container with autoBindInjectables: true, and using middlewares without explicitly binding them, the middleware resolution fails because it is not bound at the time, and then the request errors because the class is used as a middleware.

How Has This Been Tested?

A new test was created in base_middleware.test.ts which creates a Container with autoBindInjectables set to true and then using the middleware in a controller method
