Opening a folder with a # in the name throws up a 404 message

Expected behaviour

All the files are displayed as with any other folder.

Actual behaviour

The app displays a 404 message. Only after a manual refresh do the files get loaded.

Steps to reproduce

1. Create a directory structure like this:
   <nextcloud root>/Miles Morales Spider-Man (2018 - Present)/Miles Morales Spider-Man (2018) #6
   and put files in it.
2. Try to access the folder in the iOS app. The app will throw a 404 error
3. Manually drag to refresh
4. The files are now there

On every subsequent opening of the folder, the app will throw up the 404 error again, even though the file list is cached and the app already knows there are files there

Reasoning or why should it be changed/implemented?

Should be self-evident, really

No source file, test, or entry point is named. Reproduce the issue in the iOS app with a folder containing #, then trace how that folder path is opened and refreshed; done means the folder loads normally on every opening without a manual refresh.
