Travis CI tests for cordova-lib 8.0.1-dev has been failing

Travis CI tests for cordova-lib 8.0.1-dev has been failing for the following three reasons.

1. Test#022 on pkgJson.spec.js, is still using an old iOS platform version (4.3.0).

2. The pkgJson.spec.js timeout parameters are not enough. Due to network conditions, sometimes tests and NPM randomly fails.

3. Test#006 on platform.spec.js sometimes randomly fails because of missing write access. Error below can be seen when running the test.
