fix: FileInfo from View should have the correct name of a mountpoint

[susnux]

• Resolves: Group Folder titles in breadcrumbs menu are incorrect groupfolders#3068
• Resolves [Bug]: WebDAV interface returns different displayname property when requesting PROPFIND of directory vs PROPFIND of item #37541
• Resolves [Bug]: The path display of the group folder is incorrect #46670

Summary

If a mountpoint is returned from a View the name must match the view scoped name and not the global name.
For example group folders have a name like 1 or 2 (the ID), but the name of the FileInfo returned fro mthe View should be the mount point name, like First groupfolder or similar.
