[BUG] External storage 'SFTP' is shown multiple times

Actual behaviour

An exterrnal storage appears multiple times.
Only the first entry works, all other entries are empty folders.

Expected behaviour

A storage should appear exactly once.

Steps to reproduce

Reproducable with a freshly installed server 10.13.3-rc.2 (and also 10.13.2 - not a regression):

1. admin user creates an external storage "SFTP" avialable for all users.
2. admin user creates the same external storage with same config again, this time named "SFTPalice"
3. connect android client to the server (e.g. https://oc10133rc2-20231120.jw-qa.owncloud.works/)
4. log in as user alice
5. the toplevel folder list shows both, SFTP and SFTPalice, but SFTP is shown multiple times:

Extra inputs:

• it is also reproducable with 10.13.2 - so 10.13.3 is definitly innocent.
• the multiple entries of SFTP appear, as soon as the same external storage is mounted a second time with a new name.
• the issue only happens, when exactly the same path is used in both configs. If one is a subfolder of the other, no issue.

Can this problem be reproduced with the official owncloud server?
(url: https://demo.owncloud.org, user: test, password: test)
No. It depends on the setup of a second (personal) external storage.

I still consider this an android specific issue, as classic and new web UI, and desktop client show 'SFTP' exactly once.
Reproducable also with server 1.13.2

Environment data

Android version: 11

Start by reproducing the issue with two identical SFTP external-storage paths, using the listed Android and ownCloud server versions and the supplied environment details. Compare the Android top-level folder list with the classic and new web UIs and desktop client. Done means the storage appears exactly once while a second storage with the same path and a different name remains configured.
