ActivationInterceptor on get always deletes store contents

The activation interceptor when doing manual eviction always removes the entry from the loader on a get. This is done even if the entry is in the data container.

Now this is fine for a single invocation. However if a concurrent evict command comes on a different thread you can get in a state where the data is neither in the dc or loader defeating the purpose of Passivation.

The following describes this scenario

t1 -> calls get retrieves value from context (dc)
t2 -> calls evict retrieves value from context (dc)
t2 -> passivates entry (writes entry to loader)
t1 -> activates entry (removes entry from loader)
t2 -> removes entry from dc

Note this doesn't affect size based eviction.
