tdf#92517 KDE4-FileDialog: "Save as" has wrong Filter

Fixing follow
- The order of calling: first should be set the filter, after
that can be set the current filter
- change the function from "setCurrentFilter" to "setCurrentItem"
When you set the filter over "setCurrentFilter" you need the full
search string "extention|description" e.g. "*.docx|Microsoft Word.."
-  Not need the escape of slash (with that can not find
"Microsoft Word 2007/2010 XML (.docx))"
