Versions:

• commit 69b017a
• mongo 3.2.10
• node 7.0.0
• yarn instead of npm, but it shouldn't matter.

After initialising the database, there is a record in the index collection and only one (as MongoDBProvider.prototype.getIndex is requesting).

I managed to resolve that particular error by switching the mongo driver from 1.4.x to 2.0.x (given that I have mongodb 3.2.10), but there are more errors. I will make a PR for the fixed I made.
