2019 09 27 logging refactor pt2 (#765)

* Remove AKKA_CONFIG that was preventing sane logging for akka, move db-commons reference.conf to testkit so we can control testkit applications, and then rename app/server/.../application.conf to reference.conf like good libraries should do

* Update contributing.md

* update a few more links inside of contributing.md

* Run scalafmt

+The test logging for akka is controlled by the [`reference.conf`](../testkit/src/main/resources/reference.conf) file inside of testkit.
 
 This allows you to debug what is happening in our actors inside of bitcoin-s easier. For examples of what you can enable for akka to log, please look at their [logging documentation](https://doc.akka.io/docs/akka/current/logging.html#auxiliary-logging-options)
 
 The easiest thing to do to enable akka logging is to adjust the `loglevel` and `stdout-loglevel` from `OFF` to `DEBUG`.
