Bump MongoDB version in passwordless-mongostore-bcrypt-node

[danielgwood]

First off, thanks for passwordless!

At the moment I'm using it on a Windows machine, and despite my best efforts I can't convince node-gyp to behave, so I'm having to use passwordless-mongostore-bcrypt-node (very handy that exists!).

I noticed when setting up that the delivery callback was never being invoked, although I was sure I had everything right. Confirmed this by swapping to the "MemoryStore". I was able to solve my problem by changing the required mongodb dependency to ^2.2.4 in your package.json, and updating. All now works as expected and I'm getting tokens.
