Backport fix for colon in folder name on dav

[benediktg]

This issue should have already been fixed by #2727 but as it seems is not yet backported to the stable11 branch.

Steps to reproduce

1. Create a folder like "test:1"
2. Use the nextcloud client (desktop)

Expected behaviour

The folder should be synced.

Actual behaviour

The folder does not get synced by the nextcloud client, instead there is a "fatal" entry in the log.
