Error with empty single-value field

Problem/Motivation

When exporting an optional, single-valued entity reference field which does not have a value, rest_views displays a warning like:

Warning: reset() expects parameter 1 to be array, null given in /var/www/html/drupal/web/modules/contrib/rest_views/src/Plugin/Field/FieldFormatter/EntityReferenceExportFormatter.php on line 100

Steps to reproduce

Create a paragraph, which has one field which is an entity reference. Ensure this field is single-valued, and optional. Add an instance of that paragraph to a content type, then export that using rest_views.

Proposed resolution

EntityReferenceExportFormatter should check if the field actually has a value.
