Add repo.checkoutFile and repo.reset

[nshtg]

Was missing those, so I added them. Getting into the mocha beforeEach and before was confusing but I think I made it work.

[nshtg]

I figured it out - I need to run git init on the copied repository to make it work.

Please don't wonder about your inbox by travis, I was a bad boy and reset --hard all the faulty trys I uploaded here, they would just pollute the history. 😉

Must we disable node 0.8 on travis to accept these changes?

[nshtg]

Some dependencies fail to install on 0.8.

npm ERR! Error: No compatible version found: rimraf@'^2.2.8'

npm ERR! Valid install targets:

npm ERR! ["1.0.0","1.0.1","1.0.2","1.0.4","1.0.5","1.0.6","1.0.7","1.0.8","1.0.9","2.0.0","2.0.1","2.0.2","2.0.3","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.2.6","2.2.8"]

And later on

npm ERR! Error: No compatible version found: ncp@'^0.5.1'

npm ERR! Valid install targets:

npm ERR! ["0.0.0","0.0.1","0.0.2","0.1.0","0.1.1","0.1.2","0.2.0","0.2.1","0.2.2","0.2.3","0.2.4","0.2.5","0.2.6","0.3.0","0.4.0","0.2.7","0.4.1","0.4.2","0.5.0","0.5.1"]

We can probably replace rimraf completely with fs-extra, I'll check if that fixes the 0.8 error when I'm back home.

Cool, much appreciated.

[nshtg]

Okay seems like fs-extra dropped 0.8 support 2 months ago. When I'm back home I'll see if we can replace it with wrench or fs-plus.

@notatestuser
The problem is caused by the old npm version node 0.8 bundles. I 'fixed' those errors by forcing travis to update npm to a newer version for each test.

Replaced rimraf with fs-extra as proposed.

Anything left you want me to change?
