ectypes is not generating unique data each time

[nicholasf]

Ectypes should be calling the producer function each time, and the result of the function should not be being overwritten.

e.g.

․[ { properties: 
     { id: 1,
       user_id: 1,
       provider_id: 1,
       created_at: Tue Oct 16 2012 16:14:46 GMT+1100 (EST),
       is_active: true,
       message: 'ipsa quo rerum',
       thread_id: null,
       parent_id: 1 },
    id: 1,
    user_id: 1,
    provider_id: 1,
    created_at: Tue Oct 16 2012 16:14:46 GMT+1100 (EST),
    is_active: true,
    message: 'ipsa quo rerum',
    thread_id: null,
    parent_id: 1,
    alwaysTrue: [Function],
    isValid: [Function] },
  { properties: 
     { id: 2,
       user_id: 1,
       provider_id: 1,
       created_at: Tue Oct 16 2012 16:14:46 GMT+1100 (EST),
       is_active: true,
       message: 'ipsa quo rerum',
       thread_id: null,
       parent_id: 1 },
    id: 2,
    user_id: 1,
    provider_id: 1,
    created_at: Tue Oct 16 2012 16:14:46 GMT+1100 (EST),
    is_active: true,
    message: 'ipsa quo rerum',
    thread_id: null,
    parent_id: 1,
    alwaysTrue: [Function],
    isValid: [Function] },
