Edit all expense and income transactions permission excludes author field

It turns out a permission setting was missing.

Add the following to expense_tracker.permissions.yml

administer expense_tracker:
  title: 'Administer expense and income data'

A new permission will be available to select and this will give you access to set the author.

The code this permission executes is in place at src/EtTransactionAccessControlHandler.php

 /**
   * {@inheritdoc}
   */
  protected function checkFieldAccess($operation, FieldDefinitionInterface $field_definition, AccountInterface $account, FieldItemListInterface $items = NULL) {

    $restricted_fields = [
      'uid',
    ];
    if ($operation === 'edit' && in_array($field_definition->getName(), $restricted_fields, TRUE)) {
      return AccessResult::allowedIfHasPermission($account, 'administer expense_tracker');
    }
    return parent::checkFieldAccess($operation, $field_definition, $account, $items);
  }
}
