What does this PR do?

Adjusts the behavior when a comment exceeds the maximum length, preventing it from being committed at all.

How do I test this PR?

1. In the admin (/admin/configure/stream), ensure that the Limit Comment Length is unchecked, and saved.
2. In another browser, open the stream (/dev), and login as another user.
3. Back in the admin browser/tab, check the box for comment length, setting it to 5
4. In the user tab, submit the comment 123456, and see the error on the stream page indicating the comment length was exceeded.
5. In the admin tab, notice that the comment does not appear int he moderation screen.
