App does not indicate when an account is moved/migrated; following throws an error.

Bug:

Accounts that are set to migrate/move to another account do not indicate that they have been moved in the app, and when you try to follow a moved account it says: This action is not allowed. in a toast.

Expected behaviour:

Some form of indiciation that the account is moved, and/or more informative error message.

To reproduce:

1. Find account that is migrated/moved to another account in web app
2. Open that profile in Mastodon app
3. Attempt to follow

App does not crash, nor cause any major issues.
