Subject: [PATCH] BUG/MINOR: promex: Don't forget to consume the request on
 error

When the promex applet triggers an error, for instance because the URI is
invalid, we must still take care to consume the request. Otherwise, the
error will be handled by HTTP analyzers as a server abort.

This patch must be backported as far as 2.0.
