Ambiguous step detection - add support to all formatters (#648)

* added the missing impl of json/events/junit/pretty - still need 'progress' and 'junit,pretty'

* added tests for "progress formatter"

* switched from tabs to spaces in the ambiguous steps error message

* rename some_scenarions_including_failing
to     some_scenarios_including_failing

* changelog
