Makes CLI build play nice along with Android Studio

Recently, I had had an issue after opening my cordova project with Android Studio whereby the cordova build android command would constantly give me this error message.

Even though, I had all the build tools installed and everything, this issue started happening with the latest version of Android Studio. After a lot of debugging and almost giving up.

I found that the issue was happening due to local.properties file generated by Android Studio and the sdk.dir being specified in it. This change to the build script is not a permanent fix, there is something else wrong with the build process that stops it from finding the build tools.(FYI only cordova build android had this issue, a command-line based gradlew assemble task ran perfectly well).

But, this change does ensure that you can use terminal based cordova build android and you can still run and debug your app from the Android Studio as the file "local.properties" is restored afterwards.

There may be some more investigation needed to find out why the cordova build process does not work with local.properties or if this is an isolated issue that is happening on my dev environment only. This is just a temporary and quick fix to get your cordova build android working if you are also using Android Studio.
