The "I owe James Nugent (@jen20) beers" fix

- I was shooting myself in the foot all this time. Deleting all streams,
what moron dreamed that up? Moi.
- Bad config of the embedded eventstore
- The tests are working in a numb way (they know they're gonna change).
- Now the initial stream created event is gone we'll need to review the
sanity of some of the bits
- Added NLog.config to get the EventStore to speak its "logging"
