[Android app] using full URLs to change the default server fails (silently!)

[DJCrashdummy]

What happened?

this issue is somewhat related to #6873 and perhaps even #6067 (in terms of consistency).

at least in the Android app (haven't used any other app), an URL for changing the default server seems to be only accepted without https:// but there is not the slightest hint to that.
as i wanted to make sure that i have no typo or the like in my URL, i copy&pasted it... at first everything seems good (no error message; also the URL stays there after pressing ok; even a closing / gets added), but after closing and reopening the app (you have to force close the app!), the field for the default server is still empty resp. https://meet.jit.si is shown again.

this quite simple bug really drove me nuts as it is pretty hard to detect: because you have to force close the app, it sometimes seemed to work; then i even suspected that an internet connection is needed to test/confirm the new server... i tried it a gazillion times with such stupid ideas as i would never have expected this to be the issue, especially when the default resp. suggestion is shown even with the scheme! 🤦
...and even failing silently doesn't really help either. 😒

this bug sits there already for quite a while... so the mentioned version is by far not the first one effected!
but now i finally managed to nail it down. 😁
