Matchers.scala ignores timestamp format specification and only uses the TypeMatcher

In pact-jvm-matchers 2.x, a PACT like

          "$.body[0].write-timestamp": {
            "match": "timestamp",
            "timestamp": "yyyy-MM-dd\u0027T\u0027HH:mm:ss.SSS\u0027Z\u0027"
          }

erroneously rejects a value like 2017-08-11T02:54:42.522Z with the error Expected '2017-08-11T02:54:42.522Z' to be a timestamp.

This is likely to be caused by Matchers.scala using the typeMatcher instead of the timestampMatcher to match timestamps. That causes to ignore the format specification, and only accept strict ISO formats.

Yes, I can do that.

I confirm that 2.4.19 fixes the bug.

Thank you for the quick response and release, I appreciate it!
