advanced_ecommerce: remove problematic script

This script:
 - redirects with password in URL, which causes password to be in log
files and web analytics software
 - uses "immediate reindex"
 - uses manage_setLocalRoles instead of proper roles definitions (so
roles are lost when roles are regenerated and other problems)

A more proper way seem to use credential request
