Bug 495787: [Table][Tests] Create a file export to manage the paste

without using clipboard
https://bugs.eclipse.org/bugs/show_bug.cgi?id=495787

- Add the export to file of the table contents (not as menu item)
- Replace the selectAll+copy to check the table contents by the export
file check
- The first copy/paste is replaced by a command parameter with text to
copy.
