fdo#59022: revert "SfxMedium::GetOutputStream(): re-use existing XStream"

Revert commit 0c2206081de38a41597aadfb2255540d6308be63, since this
apparently causes failure to open ODF files via SMB on Linux.

Instead of changing SfxMedium, adjust the ScExportTest: when saving
XLSX files interactively, the SfxFilter::lFormat is always 0, which
causes SfxObjectShell::SaveTo_Impl not to call
SfxMedium::GetOutputStorage() at all, working around the locking issue
on WNT.
