Instance migration not possible through the WEB UI

[yasoomn]

Describe the bug

When migrating from a Mastodon server installed with Yunohost to another instance, the user is prompted for their "Handle of the new account" and "current password". Trying to move the followers this way does not work, however, the action fails with an "invalid input" message above the password field.

I suspect this has to do with Yunohost's SSO. I was able to successfully move my account to another instance when using the tootctl accounts migrate command.

Context

• Hardware: Raspberry pi 4 8gb at home.
• YunoHost version: 11.2.3
• I have access to my server: ssh/root access
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no

Steps to reproduce

1. Install the Masotodon yunohost app
2. Log into an account
3. go to Configuration > Account > Account settings > Move to a different account
4. type a username from a different instance and your Yunohost password.
5. Click on "Move followers"

Expected behavior

The page should update, and your account should be deactivated, the users should be transferred to the new account.

Logs

I couldn't find any useful log entry, feel free to ask for further details or logs.
