Add printer#EnsurePrintHeaders method

This patch adds a new `EnsurePrintHeaders` method to the
HumanReadablePrinter `ResourcePrinter`, which allows headers to be
printed in cases where multiple lists of the same resource are printed
consecutively, but are separated by non-printer related information.
