Dangling comma after position if title is empty for an honor entry

[randomnoise]

In Honors & Awards section, if you add an honor entry without the title part, a dangling comma will remain after the position part.

Sample code to reproduce the issue:

\begin{cvhonors}
  \cvhonor{Position}{Title}{}{Date}
  \cvhonor{Position}{}{}{Date}
\end{cvhonors}

Comma can be made conditional, it can appear if title is not empty.

It is nitpicking, nonetheless the comma sticks out.

I am not much of a LaTeX person, but this should be an easy fix, I would like to try.
