EJB2 CMB beans: ejbActivate callback is called after the bean creation

Called ejbActive after the create() call on home interface is incorrect by spec.

10.1.3
There are two possible transitions from the pooled to the ready state: through the ejbCreate<METHOD> and ejbPostCreate<METHOD> methods, or through the ejbActivate method. The container invokes the ejbCreate<METHOD> and ejbPostCreate<METHOD> methods when the instance is assigned to an entity object during entity object creation.
The container invokes the ejbActivate method on an instance when an instance needs to be activated to service an invocation on an existing entity object—this occurs because there is no suitable instance in the ready state to service the client’s call or the ejbTimeout method.
