16.2.54 issue when saving Package to file

Hi everyone,

Schema Browse, Package tab, Right click on a package, choose "save to file" and then "Save".
If the file(s) already exists (xxx.pks, xxx.pkb) they are not overwriten, but new files as xxx.pks.pks and xxx.pkb.pkb are created.

tested also on 16.1.53, and everything is ok.
