Props named ID may conflict with a schema resolver keyword

Problem/Motivation

Such component may breaks:

name: Test
props:
  type: object
  properties:
    foo:
      type: object
      properties:
        id:
          type: string

Because in ReferencesResolver service, we run recursively run justinrainbow resolver which

• is transforming every arrays to StdClass, included nested arrays
• add a id property when a reference is solved to keep track of the resolution

And then we do some operations on this added id property, whcih fail when we are manipulating the prop named id instead.

Proposed resolution

• Minimal: alter the id property only if a reference has been resolved
• Better: run the justinrainbow resolver only there is a $ref property.
