Nheko assumes captcha on server with captcha disabled

[Derpford]

System:

• Nheko version: Unable to retrieve due to inability to log in.
• Installation method: Appimage.
• Operating System: Debian 9
• Desktop Environment: Gnome

Actual behavior

Upon hitting "register", window pops up asking for captcha. Captcha browser page does not actually have a captcha. Registration fails with "needs Captcha" error despite server being configured for no captcha; see attached screenshot:

Expected behavior

Registration completes without captcha.

Steps to reproduce

1. Open registration window.
2. Register with a homeserver that does not use captchas. In my case, I used matrix.chatte.rs; I am unaware of other homeservers that disable captcha.
3. Attempt to register.

Logs

None found at ~/.cache/nheko. The ~/.cache/nheko folder does not exist.

Debugger backtrace

No crash, so no debugger backtrace needed.

CCing @Tecuane who owns the server I was trying to register with.

@Derpford What is the registration flow on your homeserver? Nheko currently only supports recaptcha and registration without any auth flow.

@mujx The reg flow for the homeserver is basically "register". There's no captcha and no secret key.

If you use the matrix webclient, there's nothing between inputting your email/username/password and being registered.
