Fix Jest CLI error causing Jest tests to not run (using Jest CLI v 0.…

[sevagsim]

There is an error when running npm test using Jest CLI v.0.7.1

It is due to how package.json is being used in the dependency read-package-tree. This should be excluded from the test suite.

Before: Test suite does not run
After: Test suite runs and successfully passes

I am using jest v0.7.1 on my machine as well and I have no problem. If you look at the CI on travis https://travis-ci.org/benoitvallon/react-native-nw-react-calculator the tests run correctly as well.

Depending of which version of npm you are using you may have had issues when npm install, I noticed that sometimes with the first versions of npm v3. I had to npm install 2 or 3 times.

Note that I used the following instructions, because I have NPM v2.14.7, and no matter how many times I go do npm install i get the same error.

Oh sorry, I realized that I made some modifications to the readme that made it confusing.
If you are using npm v2 npm installshould work fine.

The special instructions are for people using one of the first version of npm v3.
