Unix: Fix usability of the print properties dialog

Previous behavior:
 * Open, change setting, cancel, open again, setting was as originally (i.e. unchanged)
 * Open, change setting, accept, open, change setting, cancel, open again, the setting would be as before pressing cancel
 * Open, change setting, accept, open, press cancel without changing anything, print, the initially changed setting is not applied

New behavior:
 * Pressing cancel just cancels the changes since you opened the dialog, everything you accepted previously stays correctly selected
