ComboBox: don't focus TextField when clicking on indicator

Remove focusing editText for Combobox when clicking on indicator (when
editable is set to true). Focus on Edit Text should be set only
intentionally by user.

Before this change, when focus was set on Combobox, it automatically set
focus on editText. It was also happening when drop down indicator was
clicked. Because of that, on some platform (like Android) virtual
keyboard was appearing in case when it shouldn't be shown.
