Login Failed unsupported url on server

[MasterJubei]

Describe the bug
On the iOS version, when trying to login to my matrix server, it reports "Login Failed unsupported URL"
It works just fine on the web version, desktop client, and Android client.

To Reproduce
Steps to reproduce the behavior:

1. Choose homeserver url as my server

Desktop (please complete the following information):

• OS: iOS

Smartphone (please complete the following information):
iPhone SE 2

I purposely left the URL for my server in, in case there is an issue. It starts with a number, maybe there is a problem there?

[MasterJubei]

This is due to a trailing space. I had left the url in there, so I never realized that.
Still the form should ignore trailing spaces

Also, this may be failing without the https as well, which it should be able to handle without.

Both of these issues are fixed by #6469 and the new authentication flow which will be available in the next release.
