When using a multi-page form, if we have filefields on one of the pages we're running into an expected array warning:

Warning: end() expects parameter 1 to be array, null given in Drupal\file\Element\ManagedFile::validateManagedFile() (line 400 of core/modules/file/src/Element/ManagedFile.php).
Drupal\file\Element\ManagedFile::validateManagedFile(Array, Object, Array) (Line: 505)

This just started happening with the latest Drupal update / YAMLform update.. ?

Yep, I can duplicate the issue by creating a multistep form with a file upload on the first page.

Let's see if the attached patch works.

Patch is pretty safe so I am going to apply it.
