HPCC-11384 Fix Activity Structure issues for WsSMC

The Activity information for target clusters is returned inside the
TargetCluster structure. Existing code also returns a ServerJobQueue
structure which contains incorrect information for the target
cluster. In this fix, the code is added to not return the
ServerJobQueue for target clusters.
