Shared creation policy is not applied

[sobolev88]

Shared creation policy is not applied when ZyanComponent is imported on the server-side.
Two instances are created instead of one.

How to reproduce:

1. Creating shared service

[ZyanComponent(typeof (ITelphinService))]
[PartCreationPolicy(CreationPolicy.Shared)]
public partial class TelphinService : ITelphinService
{
public event EventHandler Answered;

public void OnAnswered(EventArgs args)
{
    Answered.SafeInvoke(null, args);
}

}

2. Subscribe to event on client-side

TelphineService.Answered += new EventHandler(TelphinService_Answered);

3. Raise event on server-side:
   [Import]
   private ITelphinService TelphinService { get; set; }

TelphinService.OnAnswered(new EventArgs());

4. Event is not raised on client-side
