Cache failed for pointer array

[sleagon]

// cache failed
games := make([]*Game, 0) // pointer array
session.Find(&games)

// cache hit
games := make([]Game, 0) // struct array
session.Find(&games)

reason:

if bean == nil || reflect.ValueOf(bean).Elem().Type() != ckt {
    // ...
}

I am not sure this pattern is designed to workaround the cache or just an issue. When we need to workaround the cache, we may write our code as shown upside. Anyway, PR #895 is provided.
