tdf#127409 Use document-specific value for "Print empty pages"

The check whether or not to print empty pages introduced by
commit cc46e7b9c7
("tdf#116537: use page #s excluding empty pages when they
are ignored") used the config option, while the option
actually being used during mail merge can be overriden by
the document settings, s. commit
8385e511aa
("tdf#117664: mailmerge: copy printer settings to new mailmerge
document").
