SAK-47748 - Creating and editing posts will no longer insert "default…

…" values when the content is removed.

The change in post.hbs didn't seem like it was part of the problem, it just looked wrong, so I fixed it! In posts.hbs, changing from a div to a span was enough to make it stop putting a <br> when the content was cleared out. The scss change fixes the same issue when editing a post. It was putting in <span></span> when the content was cleared. So, the css rule puts content in there when empty.
