testStartUsingNetworkFeature_enableHipri should be able to reconnect to Wifi Network.
Added a prefix to the already defined error message to rerun the test.
The ConnectivityManager's startUsingNetworkFeature will fail without SIM card and/or signal.
Changed the error message to check SIM card and signal and rerun the test.
