Remove invalid call of "clearFocus" in SetupWizard......

Bug: 3398097

- Also disabled logging......
- Once you call "clearFocus", onFocusChanged will be called and
  EditText will try to show the keyboard again. And while bringing up the keyboard,
  the activity is changed and it will end up with the keyboard being shown in the next activity...
