Show "select a printer" as "destination" the first the the user prints

The Spinner does not support a prompt, hence temporarily hijack the
first element and install an alternate view. Once the Spinner is touched
revert to the old behavior.

If we showed a prompt the views in the spinner cannot be recycled.
