GlobalActions: Fix Airplane Mode on/off issue

Issue: Unable to turn off Airplane mode from power button
       after phone reboot

Fix: Initialize mHasTelephony before the PhoneStateListener is
     registered to the TelephonyManager so that correct value
     of mHasTelephony is reflected when onServiceStateChanged
     callback is called.
