[BUG] Crash at login when no scheme provided and host is http

[melis-m]

Describe the bug and how to reproduce App crashes at login if no scheme specified in url and the host is http and not https. I only have a local server at the moment, so not very easily testable from the outside and maybe actually the bug is not exactly that.

Steps to reproduce the behavior:

1. Fresh install app
2. Enter a url of a piwigo server hosted on http host, without the scheme, in my case it was 192.168.x.x:8081
3. Click Login
4. App crashes, and whenever you open the app after that it tries to reconnect again and crashes, you have to uninstall

Expected behavior The login process should not crash

What did you do already

• Search whether a similar issue is already reported? -> None found
• Did you check with guest login? -> Doesn't change anything
• Did you try to reproduce it with https://www.piwigo.org/demo/ ? -> works, that's why I suppose it's the fact that my server is only HTTP that causes the crash
• Tried with the scheme, so http://192.168.x.x:8081 -> No crash
• Tried it on the android app just in case, it works though, no crash, it automatically adds the http:// in front

Smartphone (please complete the following information):

• Device: iPhone XS
• OS: iOS 15.4 beta
• App version: 2.9.4

Additional context

• Can you please give the Site URL for the Piwigo Gallery that you tried to connect to? -> Local website, so nope, sorry :\
• Which Piwigo extensions do you have installed? (If you think there might be a relationship / this is not always needed.) -> None
• Add any other context about the problem here. -> This is a completely fresh install of the app and of the server
