Contract messages with AccountId as args have multiple input fields

[DoubleOTheven]

Describe the bug See image.

To Reproduce Steps to reproduce the behavior:

This function generates the UI seen in the screenshot

        type PlayerId = AccountId;

        #[ink(message)]
        pub fn register_player(&mut self, id: PlayerId) {
            // ... code
        }

Expected behavior There should be a single input field for the UI as it is on https://polkadot.js.org/apps/#/contracts

I think this are a actually two issues:

1. Yes. A array or vector of u8 should display as hex input as in polkadot.js right now.
2. But this should be an AccountId which used to render as a list of knows accounts. The reason for this not happening are probably two:
   • You hide your type behind a type alias. Please remove. Rationale: https://github.com/paritytech/ink-workshop/pull/4#discussion_r982632381
   • Changes in ink! broke this features. Fixed in https://github.com/polkadot-js/api/pull/5237 but not yet released.
