Not `get` methods in interfaces

[magx2]

I found a bug that when an interface has a method named without get prefix it will not show in generated swagger:

This interface

public interface NoGetInterface {
    String foo();
}

will produce empty schema:

components:
  schemas:
    NoGetInterface:
      type: object

where in my opinion it should have foo field, like this:

components:
  schemas:
    NoGetInterface:
      type: object
      properties:
        foo:
          type: string
