Updates installed platform with provided www assets and new app
  configuration. This method is required for CLI workflow and will be called
  each time before build, so the changes, made to app configuration and www
  code, will be applied to platform.

@param {CordovaProject} cordovaProject A CordovaProject instance, that defines a
  project structure and configuration, that should be applied to platform
  (contains project's www location and ConfigParser instance for project's
  config).

@return  {Promise}  Return a promise either fulfilled, or rejected with
  CordovaError instance.
