Pickers in the user view throw console error when user has no access to pages/files

[afbora]

Description

I've tested the textarea and writer fields in the user view. If a role doesn't have access permissions to files or pages, an error occurs in the console and the loading spin keeps running.

title: Editor

permissions:
  pages:
    access: true
    list: false
  files:
    access: false
    list: false
    
sections:
  files:
    type: files
  fields:
    fields:
      textarea:
        type: textarea
      writer:
        type: writer

Expected behavior (one of following)

• If it doesn't have access to pages/files, that selection might not be listed at all.
• Page/file selection might be disabled.
• When a selection is made, only an empty list appears and no error is thrown for the console.

Screenshots
