Conditionally render HelperText in DatePickerInput

[Grijnak]

HelperText will take up space even when not visible. The recommended fix is to render it conditionally: react-native-paper/issues/2316.

This can lead to weird looking empty spaces and sometimes the HelperText will never be used anyway making it in the way.

You should add the datePicker input in a so it will render below the input (since default flexDirection is column in a View)

Wrapping the input in a view messes up the row because the helpertext now takes up space below the input. To be clear the issue is that it takes up space, no matter where. Even in it's own row, it will eat space even though nothing is displayed. This is what it looks like with datepickerinput in its own view on the same row:
