Describe the bug

Header matchers seem to be ignored.

I'm using docker and I've got three json mappings. They each have the same path and method matchers and each have a unique header matcher. The header matching seems to not work.

Test to reproduce

mappings:

{
    ...
    "Headers": [
      {
        "Accept": {
          "Matcher": "ExactMatcher",
          "Pattern": "application/json"
        }
      },
      {
        "my-custom-header": {
          "Matcher": "ExactMatcher",
          "Pattern": "331133"
        }
      }
    ]
}

Other related info

Something interesting is that the request match results don't seem to include anything about headers/exact matchers. Am I doing something wrong?

{
  ...
  "RequestMatchResult": {
    "TotalScore": 2.0,
    "TotalNumber": 2,
    "IsPerfectMatch": true,
    "AverageTotalScore": 1.0,
    "MatchDetails": [
      {
        "Name": "PathMatcher",
        "Score": 1.0
      },
      {
        "Name": "MethodMatcher",
        "Score": 1.0
      }
    ]
  },
  "PartialMappingGuid": "b5533495-a223-458d-b22a-1654ec0cd173",
  "PartialMappingTitle": null,
  "PartialRequestMatchResult": {
    "TotalScore": 2.0,
    "TotalNumber": 2,
    "IsPerfectMatch": true,
    "AverageTotalScore": 1.0,
    "MatchDetails": [
      {
        "Name": "PathMatcher",
        "Score": 1.0
      },
      {
        "Name": "MethodMatcher",
        "Score": 1.0
      }
    ]
  }
}

Changed the mapping format and it started working.
