sc: test failure depending on order of execution

[Xisco Fauli]

Hello,

it seems there is a test in sc/qa/unit/subsequent_export_test2.cxx that 
fails depending on the order of execution.

If testTdf121260 is executed before testTdf107586, then it passes, 
otherwise, it fails with

##Failure Location unknown## : Error
Test name: ScExportTest2::testTdf121260
An uncaught exception of type com.sun.star.container.NoSuchElementException
- 
/home/tdf/lode/jenkins/workspace/lo_gerrit/Config/linux_clang_dbgutil_64/package/source/zippackage/zipfileaccess.cxx:263: 
at 
/home/tdf/lode/jenkins/workspace/lo_gerrit/Config/linux_clang_dbgutil_64/package/source/zippackage/zipfileaccess.cxx:263

which means the file 'xl/charts/chart1.xml' doesn't exist in the zip 
file and parseExport fails. See 
https://gerrit.libreoffice.org/c/core/+/147622

Anyone has any idea why the file is not created if testTdf107586 is 
executed first ?

Regards
