Sample XLS #1

Open one of the attached XLS files in Calc, save as XLSX, and try opening them in Excel.

=> Excel crashes.

One could say it's a problem in Excel, and it shouldn't crash, which is true, but since it doesn't crash with the file it creates, Calc should not export such a file, either.

Observed using LO 25.8.0.0.alpha0+ (41ab24cecd6ad74312843f113d2faa13259cdb7d) / Windows.

This is a regression from the following commit in 25.8:

Opening xls#1 with Excel and saving it as XLSX:
- Open fine with Calc and Excel.
But after opening with Calc, XLSX saved with Excel, doesn't save the checkboxes.
