Bug 877800

Description of problem:
There is value P%2b1%3dV%2b1%26P%2b2%3dV%2b2%26P%2b3%3dV%2b3 instead of P+1=V+1&P+2=V+2&P+3=V+3 when using netunity v2 as a remote producer.

This error is present when using portlets Interaction State and Navigational State.

How reproducible:
Register netunity v2 as a producer using http://netunitysoftware.com/wsrp2interop/WsrpProducer.asmx?Operation=WSDL&WsrpVersion=Two

Steps to Reproduce:
1. start portal and register the producer
2. go to application registry 
3. import applications
4. add Interaction State and Navigational State into page. 

  
Actual results:
Interaction State
 - when click on Set using Anchor (HREF) -> P+1=V+1&P+2=V+2&P+3=V+3 or Set using Form Submit (Action) -> P+1=V+1&P+2=V+2&P+3=V+3 button Last Portlet InteractionState: P%2b1%3dV%2b1%26P%2b2%3dV%2b2%26P%2b3%3dV%2b3 

Navigational State
 - Set in Render URL -> P+1=V+1&P+2=V+2&P+3=V+3
 - Set in Blocking Interaction URL -> P+1=V+1&P+2=V+2&P+3=V+3 button

Expected results: 
instead of P%2b1%3dV%2b1%26P%2b2%3dV%2b2%26P%2b3%3dV%2b3  there should be P+1=V+1&P+2=V+2&P+3=V+3.


Additional info: Navigational State -> Set in PBIA Response works fine.
