Add ContactManager0001Test

So I have no clue about unit testing so I basically took the tags0001 and edited it for the contact component to try and get a feel for how it all worked. I have no clue how to even run the tests. But would be interesting to get some feedback on whether it works (i.e. the tests pass) and if there's anything I missed out :)

Edit: I'm hopeful that the travis build passing test below means it's working. Anyone know this to be true?
