Message:

REST API: Allow sending an empty or no-op comment update.

In general, updates that don't actually change anything should succeed. [39371] added tests for other object types, and this commit fixes empty updates for comments and adds the missing test.

Merges [39597] to the 4.7 branch.

Props jnylen0.
Fixes #38700.
