NPE when all child enpoints of nested loadbalance endpoint failed
-----------------------------------------------------------------

                 Key: SYNAPSE-845
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-845
             Project: Synapse
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.1
            Reporter: Miyuru Wanninayaka
             Fix For: NIGHTLY


When nested LB endpoint created like,

<endpoint name="LB1">
       <loadbalance algorithm="org.apache.synapse.endpoints.algorithms.RoundRobin">
           <endpoint>
               <loadbalance algorithm="org.apache.synapse.endpoints.algorithms.RoundRobin">
                   <endpoint>
                       <address uri="http://localhost:9000/services/LBService1"/>
                   </endpoint>
                   <endpoint>
                       <address uri="http://localhost:9001/services/LBService1"/>
                   </endpoint>
               </loadbalance>
           </endpoint>
           <endpoint>
               <loadbalance algorithm="org.apache.synapse.endpoints.algorithms.RoundRobin">
                   <endpoint>
                       <address uri="http://localhost:9002/services/LBService1"/>
                   </endpoint>
                   <endpoint>
                       <address uri="http://localhost:9003/services/LBService1"/>
                   </endpoint>
               </loadbalance>
           </endpoint>
       </loadbalance>
   </endpoint>

When both servers running on port 9000 and 9001 down, following NPE will be thrown because
loadbalance endpoint does not have a definition.
