BUG/MINOR: stats: make "show stat typed desc" work again

As part of the changes to support per-module stats data in 2.3-dev6
with commit ee63d4bd6 ("MEDIUM: stats: integrate static proxies stats
in new stats"), a small change resulted in the description field to
be replaced by the name field, making it pointless. Let's fix this
back.

This should fix issue #1291. Thanks to Nick Ramirez for reporting this
issue.

This patch can be backported to 2.3.
