[Fuego] [PATCH 1/2] LTP:ltp_process: dont crash if no sheets are generated

[Daniel Sangorrin <daniel.sangorrin@toshiba.co.jp>]

This fixes the following error that occurs when running the rtonly spec,
which does not generate any sheet.

Traceback (most recent call last):
  File "ltp_process.py", line 338, in <module>
    book.save('results.xlsx')
  File "/usr/lib/pymodules/python2.7/openpyxl/workbook.py", line 232, in save
