stringifying location for more consistent json parsing - address #945

[larryprice]

I started running into issues when formatting cucumber reports as JSON. With the default JSON gem (also I believe 'oj' and 'yajl'), it seems that the JSON formatter has started stringifying the location object on steps as hashes instead of using the to_s method found in cucumber-ruby-core.

Desired Output:

"location": "features/step_definitions/selenium/selenium.rb:8"

Undesired Output:

              "location": {
                "filepath": {
                  "filename": "json_spec-1.1.4/lib/json_spec/cucumber.rb"
                },
                "lines": {
                  "data": [
                    "5"
                    ]
                  }
                }

This issue does not occur when running the spec tests using the json_spec gem, but happens every time with the classic ruby JSON gem (1.8.3). I added a to_s call when creating the match hash, which doesn't seem to have any other repercussions besides fixing this bug.

Fixes #945.

In the end we want the the string that action_location#to_s returns in the JSON file, so I see no problem with calling it explicitly in the JSON formatter.
