[Bug]: Cannot add to list on GoToSocial instance

[raspbeguy]

Describe the bug

When I try to add an account on a list, there is an error : "Network error: temporary redirect". I'm using a GoToSocial instance and adding to list is possible from others clients like Tusky.

I suspect this is because an extra / in the request URL (see the logs later). And indeed, when I curl the URL, it redirects (301) to the same URL without the /. So I think Tuba should either support 301 redirections or call the URL without trailing /.

Steps To Reproduce

1. Go to the page of the account you want to add to a list.
2. On the "three dots" menu on the right of the window bar, select List.
3. Click on the "+" in front of the list you want the account to be added.
4. See the error.

Nice catch!

#760 will fix the urls, though I'm unsure about the redirects. Libsoup is supposed to handle it and I can only opt out, I'll see if I can manage to make a minimal reproducer and report it upstream
