Mark getFragments as @VisibleForTesting

Proguard was stripping out the method, and that somehow causes the
test to be stuck at Instrumentation.startActivitySync(), causing
lab devices to be stuck at this test for some 5 minutes.

Test: adb shell am instrument -w -e class \
      com.android.emergency.edit.EditInfoActivityTest \
      com.android.emergency.tests
