REST API: Sending empty array for single = false meta returns a 500 error if the there is not meta do delete

[goaroundagain]

If the Block Editor sends with WordPress 5.7 an empty array for single = false meta and there is no meta to delete, it returns a 500 error.

The default behaver of the Block Editor is to send an empty array for unset single = false meta.

This bug was introduced through this fix: https://core.trac.wordpress.org/ticket/50790

I will provide an updated unit test
