Only launch fingerprint settings after enrollment if it's from the summary controller

Fixes: 133822544

Test: No more multiple instances of fingerprint settings after enrolling
      from within the settings page

Test: adb shell am start -a android.settings.BIOMETRIC_ENROLL does not
      send the user to fingerprint settings after completing enrollment
