fix expansion-timestamp in multiple appndProcTermTo CSVs
There is an issue that the usage of multiple appndProcTermTo CSVs like the terminologiesMetadata.csv and processedTerminologies.csv in TerminoloGit, the expansion timestamp from the last appndProcTermTo CSV is beeing taken.
Maybe a good solution would be to use one timestamp through all of the appndProcTermTo CSVs.
