3 `build.spec.js` tests are disabled

Currently 3 tests in `build.spec.js` are disabled because I couldn't figure out what was wrong with them and how to fix them.

(My current theory: I moved the function call https://github.com/apache/cordova-windows/blob/8c07366fb8d784563a2fefe7d9bb326cb1cb721d/template/cordova/lib/build.js#L61 outside of the `.then` below where it was before and called via another method https://github.com/apache/cordova-windows/blob/dccdab98753abdbd39dd81259df6cfe7ee2ae81d/template/cordova/lib/build.js#L311, which somehow changes how the Error is perceived by the test script)
