Fix missing dots in 'loo_moment_match'

[paul-buerkner]

This PR fixes a typo in loo_moment_match that prevented ... to be passed to the loo_moment_match_split method. This causes trouble as soon as any additional argument is passed to the helper functions of moment matching. I should have seen this earlier (before the loo release) but unfortunately I didn't.

@jgabry we should make another small CRAN update as soon as possible to make moment matching generally usable with additional arguments.

Thanks for spotting and fixing this mistake! Should have been more thorough with the tests to catch this...

[jgabry]

Thanks for fixing. I'll have time to do another CRAN submission Thursday night or Friday. @topipa if you have time before then can you add a test for this on the fix-missing-dots branch?

[topipa]

Test added. Thanks for the quick response on this!

[jgabry]

Sorry for the delay on this. Resubmitting today.
