Add logs for widget picker image test

The screenshot test is failing in udc-qpr because the search bar is smaller when the screenshot is taken than what the reference image is. Adding logs to figure out what might be causing the search bar to be differently sized in udc-qpr tests (in main WidgetPickerImageTest passes, as well as udc-qpr locally)
