In general, updates that don't actually change anything should succeed.
<a href="https://core.trac.wordpress.org/changeset/39371">[39371]</a> added tests for other object types, and this commit fixes empty updates
for comments and adds the missing test.
Fixes <a href="https://core.trac.wordpress.org/ticket/38700">#38700</a>.</pre>
