Already fixed in the version 4.1.
The module is always engaging in Axis2 as it is only possible to engage it globally (http://axis.apache.org/axis2/java/core/docs/adv-userguide.html). Thus it is not possible to control it with the parameter modules.
But it is possible to enable/disable the WS-Addressing for a specific service with the parameter enable-wsa in the version 4.1 (By default, it is disabled).
Fixed in branch petals-entreprise-3.1.x
