Fix parsing method calls with null arguments in Java code
Fix parsing method calls with null arguments in Java code

In Java, "null" is represented as a keyword, not as the integer 0. The
old code assumed the latter. Code such as

    translate("fooBar", "fooBar", null);

would thus not be detected by lupdate when parsing Java files.
