All of the vendor files seem to be throwing exceptions

[sathrall]

I noticed that there are missing vendor files because there's an exception thrown for each of them when any template attempts to render.

An exception has been thrown during the rendering of a template ("No file could be resolved for the stream path 'assets://vendor/fontawesome-iconpicker/dist/css/fontawesome-iconpicker.css'.").

This is a common problem. See doc: https://learn.userfrosting.com/troubleshooting/common-problems#an-exception-has-been-thrown-during-the-rendering-of-a-template
