I've found one fix :

comment this line in demo/demo_1/message.py :

#z3c.zalchemy.createTable('message', 'DemoEngine-1')

add this lines in demo/demo_1/configure.zcml

  <alchemy:createTable
      table="message"
      engine="DemoEngine-1"
      />

Explication : z3c.zalchemy.createTable('message', 'DemoEngine-1') can't 
work because utility registered in zcml is really registered at end of 
configuration parsing. Thereof 
z3c.zalchemy.interfaces.IAlchemyEngineUtility can't be caught.
