Silence warning in QPrintDialog

Selecting "Print all" at page range options and accepting the
dialog prints a warning message:

"QPageRanges::addRange: 'from' and 'to' must be greater than 0"

This happens because QPrintDialog tries to clear the printer's range
collection by setting 'from' and 'to' to zero - which is an invalid
page number. Avoid the validation method by setting QPageRanges
directly to a clean instance.

Pick-to: 6.1
