Nouveau - Activity comments are hidden

[r-a-y]

There's a bug that hides all activity comments for being shown in Nouveau.

I have narrowed it down to this commit on Github:
​https://github.com/buddypress/next-template-packs/commit/b1846eeef85b806fbf5d4cfa3efd1e61054079fc

The problem is due to a check for $( comment_parents ).find( 'li.show-all' ), which will return an object. If we want to check for the existence of li.show-all, we need to check the length of the object.

@imath - Can I get you to verify that this patch is okay?

@r-a-y Sure :)

Green lights for me. Thanks a lot for your work : i can't believe i forgot the length in the check 🙄
