LOG_TRAFFIC and DUMP_ENTITY TestProperties not honored.

When running examples/json-moxy with jersey 2.22.2, the following output is seen:

```
Feb 07, 2017 2:34:06 PM org.glassfish.jersey.filter.LoggingFilter log
INFO: 1 * Sending client request on thread main
1 > GET http://localhost:9998/test
1 > Accept: application/json

{"a":"a","b":1,"c":1}
```

This stopped working as of 2.23.
Seems like LoggingFeature was introduced with that version.
