Problematic encoding of WebDAV URLS

## Describe the bug
Multiple WebDAV clients have problems using the way the WebDAV URL of folders is encoded in the OCIS Web user interface. When I use the copied URL with e.g., the cadaver webdav client or as a sync-location for my password manager Enpass, they both fail to open that URL.

Currently the URL looks like this:
`https://192.168.1.23:9200/dav/spaces/de6602fa-3c8d-4055-884b-02106220a256%244c510ada-c86b-4815-8820-42cdf82c3d51/New%20folder` with the dollar sign in the middle encoded as `%24`, which does not work. Replacing the `%24` with the actual `$` character makes it work for both clients.

My guess is, that the encoded URL does not match the actual data returned the XML response. Using curl to call PROPFIND on the URL
```console
AUTH="$(echo -ne "einstein:relativity" | base64 --wrap 0)"
curl --insecure -H "Authorization: Basic $AUTH" -XPROPFIND \
'https://192.168.1.23:9200/dav/spaces/de6602fa-3c8d-4055-884b-02106220a256%244c510ada-c86b-4815-8820-42cdf82c3d51/New%20folder' \
| xmllint --format -
```
gives this output:
```xml

You can see, that in the XML response the `%24` is decoded while the `%20` is not. My guess is that the WebDAV clients can't handle the `%24`/`$` mismatch.

## Steps to reproduce
1. Set up OCIS with Demo Users
2. run OCIS with PROXY_ENABLE_BASIC_AUTH=true
3. create a folder "New Folder" in the Web Interface for user einstein
4. copy the WebDAV URL for the "New Folder"
5. try to access the folder using cadaver for example: `cadaver 'https://192.168.1.23/dav/spaces/5d5f37f9-0ecf-4717-a677-840bf5fcb234%2492945bd5-00d5-4784-80f4-48b92d0ce702/New%20folder'`

## Expected behavior
The user interface should show the URL as it is used within the WebDAV protocol:
`https://192.168.1.23:9200/dav/spaces/de6602fa-3c8d-4055-884b-02106220a256$4c510ada-c86b-4815-8820-42cdf82c3d51/New%20folder`

Which allows cadaver to open it:
```
> cadaver 'https://192.168.1.23:9200/dav/spaces/de6602fa-3c8d-4055-884b-02106220a256$4c510ada-c86b-4815-8820-42cdf82c3d51/New%20folder'
[certificate warning removed]
Authentication required for 192.168.1.23:9200 on server `192.168.1.23':

```
My password manager also works with this URL.

## Actual behavior
Currently shown URL: `https://192.168.1.23:9200/dav/spaces/de6602fa-3c8d-4055-884b-02106220a256%244c510ada-c86b-4815-8820-42cdf82c3d51/New%20folder` (`$` encoded as `%24`)

Cadaver gives this error after entering the password:
```
> cadaver 'https://192.168.1.23:9200/dav/spaces/de6602fa-3c8d-4055-884b-02106220a256%244c510ada-c86b-4815-8820-42cdf82c3d51/New%20folder'

## Setup
Please describe how you started the server and provide a list of relevant environment variables or configuration files.

Running OCIS in a docker container

```console
docker run --rm -it --mount type=bind,source=$PWD/ocis/ocis-config,target=/etc/ocis -e IDM_CREATE_DEMO_USERS=true owncloud/ocis init
docker run --name ocis_runtime --rm -it -p 9200:9200 --mount type=bind,source=$PWD/ocis/ocis-config,target=/etc/ocis --mount type=bind,source=$PWD/ocis/ocis-data,target=/var/lib/ocis -e OCIS_LOG_LEVEL=info -e OCIS_INSECURE=true -e PROXY_HTTP_ADDR=0.0.0.0:9200 -e PROXY_TLS=true -e OCIS_URL=https://192.168.1.23:9200 -e PROXY_ENABLE_BASIC_AUTH=true -e WEBDAV_LOG_LEVEL=DEBUG -e OCIS_LOG_PRETTY=true -e IDM_CREATE_DEMO_USERS=true owncloud/ocis

I don't know if this is somehow related to #4676
