Steps to reproduce:

• login in PlatformUI with a user that does not have the Role containing content/versionread
• View any Content

the console should contain the following error:

Uncaught TypeError: versions.forEach is not a function

The error is located in https://github.com/ezsystems/PlatformUIBundle/blob/v1.6.1/Resources/public/js/models/extensions/ez-contentinfo-base.js#L60 where the error handling is missing.
