Message:

REST API: Fix fatal error when making HEAD requests with _fields filter.

In [59889] the REST API controllers were adjusted to perform less work when responding to HEAD requests. The WP_REST_Response body would now be null, which caused issues with filters that expected the response body to be an array.

This commit sets the response body to be an empty array when preparing the response instead. The body will still be discarded, but this provides better backward comppatibility with code that assumes an array will be used.

See #56481.
