XLSX Exporter keeps only one line from Ethics approval information

One of the projects (https://daisy.lcsb.uni.lu/project/7) has multiline comment on institutional ethics field:

```
Has ethics approval from the University of Magdeburg.
Ref: 78/11, Ethikkommission der Medizinischen Fakultät der Otto-von-Guericke-Universität Magdeburg
```

Only first line is included in the export.

There seems to be non-standard end of the line character. ^M?
