RFR: 8378417: Printing All pages results in NPE for 1.1 PrintJob

[Prasanta Sadhukhan]

After [JDK-8373239](https://bugs.openjdk.org/browse/JDK-8373239):, Printing ALL pages results in NPE for 1.1 PrintJob because of lack of set pageranges citing

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException: Cannot invoke "javax.print.attribute.standard.PageRanges.getMembers()" because "range" is null
        at java.desktop/sun.print.PrintJobDelegate.updateAttributes(PrintJobDelegate.java:529)
        at java.desktop/sun.print.PrintJobDelegate.printDialog(PrintJobDelegate.java:424)
        at java.desktop/sun.print.PrintJob2D.printDialog(PrintJob2D.java:65)
        at java.desktop/sun.awt.windows.WToolkit.getPrintJob(WToolkit.java:644)
        at java.desktop/sun.awt.windows.WToolkit.getPrintJob(WToolkit.java:629) 

A null check is now added as we are now removing PageRange attribute if not set..It works fine for PrinterJob but fails for 1.1 PrintJob as PrintJobDelegate.updateAttributes called in 1.1 PrintJob use pageRange variable without checking if it exists.
