Fix Comments controller destroy declaration

[bliof]

The destroy was defined in the create method 🤪

Oh wow 😱.

I wonder if the default action is actually working fine, since nobody has actually reported any issues while deleting comments that I recall 🤔.

@bliof I tried the update branch feature here but seeing the same code coverage error elsewhere so I think the issue is I can't rebase on my side. Can you please rebase or push an empty commit to re-run CI? I will approve and merge this change once build passes. Thank you.

Ok it's been rebased and build is now running. We just need tests to satisfy the Codecov patch check. Would welcome an update. Thank you.
