Fix lockdown admin configured networks in TestDPC

* In the framework, 'isLockdownAdminConfiguredNetworks'
  was renamed to 'hasLockdownAdminConfiguredNetworks' and
 'setLockdownAdminConfiguredNetworks' was renamed to
 'setConfiguredNetworksLockdownState'.
* Updated TestDPC to use the new names of these APIs.
