configuration migrate: Remove duplicate infix-meta:version when migra…

…te config

when migrate configs the yang data produced was this:
  "infix-meta:meta": {
    version: "1.0"
    "infix-meta:version": "1.1"
  },

duplicate node, resulting in failed migration of startup configuration, always replace
whole node.
