BUG/MINOR: promex: Remove Help prefix repeated twice for each metric

When the support for modules was added, the function producing the #HELP
line of each metric was refactored. Since then, the prefix "#HELP
<metric-name>" is printed twice because a code block was not removed. It is
now fixed.

This patch must be backported to 3.0.
