Bug 1030251

Given a KB with the two rules below:

 rule "Insert Info "
 when
 then
     insert(  "aaa " );
     insert( new Integer( 12 ) );
     insert( new Double( 4.0 ) );
 end
 
 rule "React "
 when
     Integer()
     accumulate (
                  $n : Double( ) and
                       Double(  ),
                  $x : count( $n )
                )
     String( )
 then
     System.out.println(  "Rule fires" );
 end

The rules work normally in the first session created from the KB.
When any additional session is created and used, the SegmentMemories are restored from the SM Prototypes.
Unfortunately, the AccumulateNode -> RuleTerminalNode segment is restored twice, once when the "aaa"
triggers the appropriate Beta Node, and once when the subnetwork updates the RIA node.
The latter overwrites the already existing segment, overriding the partial link bits.
