Describe the bug

Admin API is used to create a mapping which has some sort of request body match, but other matches get created except body.

Expected behavior:

Body match should appear when querying GET __admin/mappings.

Test to reproduce

Admin API is used to create the following mapping.

var model = new MappingModel
{
    Request = new RequestModel
    {
        Path = "test",
        Body = new BodyModel
        {
            Matcher = new MatcherModel
            {
                Name = "RegexMatcher",
                Pattern = "hello"
            }
        }
    },
    Response = new ResponseModel
    {
        Body = "world"
    }
};
await RestClient.For<IWireMockAdminApi>("http://localhost").PostMappingAsync(model);

The response from GET __admin/mappings

[
  {
    "Guid": "486b7f76-f29a-4928-9f16-bf6c3a2ce8f2",
    "Request": {
      "Path": {
        "Matchers": [
          {
            "Name": "WildcardMatcher",
            "Pattern": "test",
            "IgnoreCase": false
          }
        ]
      }
    },
    "Response": {
      "Body": "world"
    }
  }
]

@yunj
The root cause is that you don't provide the Methods on you wish to match. The current code does not return the bodymatcher if there are no Methods defined or if the methods have a 'get'.

I'll investigate why I did add this check in the code.

For your solution now: set the Methods.
