tdf#87973 XLSX export: fix lost file names in modified links

Calculate new indexes for external reference files to export it to xlsx.
These indexes are calculated only temporary, only for exporting.

Much better solution would be to change the indexes permanently,
but the original indexes are stored so many places in the code
(for example it is stored in cells formula tokens converted to string).
So it would be a much bigger refactoring to be able to delete an
external reference permanently... even just to reorder the indexes,
require to modify a lot of code.
