bug fix. by Large flavor, ViewFunctions::static_file

static_file's input is in example, "/static/css/main.css".But setuped application's file path is:

- In Other Flavor, just ./static/css/main.css
- In Large Flavor, ./static/admin/css/main.css or ./static/web/css/main.css 

I can not get $fullpath in Large Flavor. So I fixed this point.
