For every feature a new GUID should be defined (SharePoint#1713)

It is too tempting to copy and paste the code in her resulting that ever SPFx solution that deploys assets uses the same GUID :D

Just to make things clear :D

 Note the following about the added json definitions:
 
+* Make sure you define a **unique GUID** for the id property inside the feature section
+
 * You can technically have multiple features in the package because **features** is a collection; however, this is not recommended.
 
 * **elements.xml** is referenced under elementManifests so that it's packaged properly for the actual feature XML structure as an element manifest file.
