Per FieldHandlerInterface::expand(), field handlers expect an array of
field values.  The source entity object passed into expandEntityFields()
often has an inconsistent structure across its various field properties,
sometimes holding a single value, sometimes holding an array of values (as
expected), and sometimes holding an array of composite field parts for a
single field value.  Consistently providing field handlers the field values
in the structure they expect allows them to expand each field value
correctly.
