[BUG] CSRF token parameter logged in OpenAllModules servlet #972

Discovered during #918.

src/main/java/servlets/admin/moduleManagement/OpenAllModules.java logs the submitted CSRF token on every request, before the admin session is validated:

Object tokenParmeter = request.getParameter("csrfToken");
log.debug("Token Param: " + tokenParmeter.toString());

log4j2.properties sets the servlets logger to debug and sends it to the rolling log file, so this runs by default and puts valid admin CSRF tokens in the log.

It also throws a NullPointerException when the csrfToken parameter is missing, because .toString() is called on null.

Fix: remove the line, or log only whether the parameter was present.
