Foreign keys for self-referencing tables are not created.

For example, have a look at this entity:

public class EventInfo
{
    public int Id { get; set; }
    public virtual ICollection<EventInfo> ChildEventInfos { get; set; }
    public int? ParentEventInfoId { get; set; }
    public virtual EventInfo ParentEventInfo { get; set; }
}

and this configuration of it:

modelBuilder.Entity<EventInfo>()
    .HasOptional(x => x.ParentEventInfo)
    .WithMany(x => x.ChildEventInfos)
    .HasForeignKey(x => x.ParentEventInfoId);

Created table lacks FK ParentEventInfoId REFERENCES EventInfo (Id).

The problem seems to be in CreateDatabaseStatementBuilder.GetCreateTableStatements, where respective association type is filtered out since its Constraint.RoleTo.Name is "EventInfoSelf", not "EventInfo".
