YADE should not throw error "no matching file found" when parameter overwrite_files = false is set

As of situation

• when YADE is configured with parameter overwrite_files = false JADE throws an error

   letzter aufgetretener Fehler           = SOSJADE_E_0100: es wurde keine Datei mit einem Namen gefunden der dem regulären Ausdruck '^.*_22.01.2015\.xls$' entspricht.
  SOSJADE_E_0100: es wurde keine Datei mit einem Namen gefunden der dem regulären Ausdruck '^.*_22.01.2015\.xls$' entspricht. 
  

Expected behavior

1. When file is not present at target serer / target directory, YADE should transfer the files from source to target without any error
2. When file is ALREADY present and target server / target directory, YADE should print an appropriate warning i.e.

   [WARN] transfer skipped for file xxx due to overwrite constraint
