`schemas.[name].properties` are ignored when `allOf` is present

[wei]

Describe the bug properties are ignored when allOf and properties are both present at the same level.

To Reproduce Steps to reproduce the behavior:

1. Example schema: https://gist.github.com/wei/af7976a2bbdf4e0c4ed1013559d58578/revisions#diff-bea257c04d5327bd1cb2994a43299a45f926bf90e20e091a5e38d6faae3619dd

   Pet:
     description: A pet.
     allOf:
       - $ref: "#/components/schemas/NewPet"
     properties:
       id:
         type: integer
         format: int64
   

2. We get

   export type Pet = NewPet;
   

Expected behavior

export type Pet = NewPet & {
  id: number;
};
