Update HoneybadgerErrorHandler.java to avoid deprecated Logger call

[JasonTrue]

I noticed a soft deprecation warning coming from recent versions of Play in the process of updating HoneyBadger to "officially" support Java 11/12.

honeybadger-java/honeybadger-java/src/main/java/io/honeybadger/reporter/play/HoneybadgerErrorHandler.java:[76,18] [deprecation] error(String,Throwable) in Logger has been deprecated

Replacing this call should be trivial, but I want to make sure I understand the implications before I roll it in.
