Connection Test fails with Basic Auth with 2.0.1

I am using Basic Auth to protect my wallabag 2.2.3 installation. This was and is working fine with the 1.12.2 app. However with 2.0.1 the connection test is failing.

I entered the proper connection settings and Autofill is working. The client registers, gets a secret (that matches with what the webclient shows). Still, after navigating to the main screen, the proposed connection test fails.

It says: **API access test failed**
Unknown error:
AuthorizationException: HTTP response: 401 Unauthorized

On the server, I see this log:

```
"GET / HTTP/1.1" 302 4616 "-" "okhttp/3.8.1"
"GET /login HTTP/1.1" 200 1546 "-" "okhttp/3.8.1"
"POST /login_check HTTP/1.1" 302 832 "-" "okhttp/3.8.1"
"GET / HTTP/1.1" 200 6837 "-" "okhttp/3.8.1"
"GET / HTTP/1.1" 200 6837 "-" "okhttp/3.8.1"
[auth_basic:error] [pid 4526] [client 189.4.72.29:9498] AH01614: client used wrong authentication scheme: /api/version.json
"GET /api/version.json HTTP/1.1" 401 4543 "-" "okhttp/3.8.1"
"POST /oauth/v2/token HTTP/1.1" 401 684 "-" "okhttp/3.8.1"
```

Looks like one of those requests is made without basic auth. If that is the problem, it should be an easy fix.
