Fix adb related commands when path has spaces

When CLI is installed in directory, which has space (or the path above this dir has spaces) and android-sdk is not installed, we are trying to execute adb from our resources. This is failing due to missing `"` in our commands.

Fixes NativeScript/nativescript-cli#470
