Error: failed to register user when URL of server ends with "/"

[tfriedel]

I setup a custom server, but when trying to register I got the error:
"Error: failed to register user"

It was not obvious that the reason I got this error was because the URL
looked like http://myserver.com:8888/ , i.e. ended with a slash.
After I changed it to http://myserver.com:8888 registering worked.

This should be easily fixable, for example by stripping the trailing slash.

Thanks, this is probably due to us using string formatting for our URLs... I've been meaning to use proper URL parsing and building but never got the motivation to do it. I'll try to get around to it now

If anyone wants to take a shot at this in the meantime, looks like we can use reqwest::Url::join
