Header templating doesn't work when simulation has a header matcher

[tommysitu]

Noticed a very likely related bug in templating:

If I have a "headers" matcher in my simulation, e.g.:

          "headers": {
            "Authorization": [
              {
                "matcher": "glob",
                "value": "Bearer test-*"
              }
            ]
          }

then in the response body a {{ Request.Header.Authorization }} returns an empty string. But if I remove the request "headers" matcher, I get the correct value printed to the response. @tommysitu
