Call to undefined method Drupal\file\Entity\File::url() [#3545937]

Problem/Motivation

When I place the element on a page and move through the form, I see this error.

Error: Call to undefined method Drupal\file\Entity\File::url() in Drupal\webform_dropzonejs\Element\WebformDropzonejs::processDropzoneJs() (line 92 of /Users/andy/Sites/bhcclocalgov/docroot/modules/contrib/dropzonejs_webform/src/Element/WebformDropzonejs.php)

Steps to reproduce

Set up a multiple page webform
Place a dropzone webform element on the first page
Place another element on the second page
View the webform, Upload files and go to the next page.
Next button will hang, See error above in logs, and on viewing submissions the file will not be there.

Proposed resolution

I think 'path' => $file->url(), in /src/Element/WebformDropzonejs.php line 92 should be 'path' => $file-> getFileUri(),
See https://api.drupal.org/api/drupal/core%21modules%21file%21src%21FileInte...

Looking closely, this is tied to having the element on a multiple page form.
Here's an example

page_one:
  '#type': wizard_page
  '#title': 'Page one'
  fieldset:
    '#type': fieldset
    '#title': Fieldset
    dropzone:
      '#type': webform_dropzonejs
      '#title': Dropzone
      '#multiple': true
page_two:
  '#type': wizard_page
  '#title': 'Page two'
  fieldset_2:
    '#type': fieldset
    '#title': 'Fieldset 2'
    some_text:
      '#type': textarea
      '#title': 'Some text'
