This allows one, for example, to set a custom \date in the header-includes of the rmarkdown yaml frontmatter. Without this conditional, the custom \date in the frontmatter would be overridden by a (potentially empty) date from this template later.

This reverts commit 3f1f58e. The reason for reverting this change is that it led to an undesirable behavior change. Documents with no explicit date specified now have a date printed, because the default title block will include a date if no `\date` command is used. The empty `\date{}`, by contrast, suppressed the date, which is the desirable behavior. PR #10687 was motivated by the desire to include a custom `\date` in the frontmatter via header-includes. I think that aim can be achieved more simply by simply setting the `date` variable. In markdown you can even use `date:` in metadata and put some raw LaTeX there.
