[Bug]: When signing up, entering a duplicate email or username results in spinning button forever.

Requirements

• Is this a bug report? For questions or discussions use https://lemmy.ml/c/lemmy_support
• Did you check to see if this issue already exists?
• Is this only a single bug? Do not put multiple bugs in one issue.
• Is this a server side (not related to the UI) issue? Use the Lemmy back end repo.

Summary

When signing up for a new account if a duplicate email address or username is entered, there is no indication of a possible conflict. When clicking on the "Sign Up" button, a spinner just continues forever. If the lemmy backend is inspected it throws an error about a duplicate email or username. This is not reflected in the UI.

Suggest there be a check for a duplicate email or username before the user clicks "Sign up".

Steps to Reproduce

1. Find a Lemmy instance.
2. Sign up with a duplicate email or username.
3. Spinner goes on and on.

Technical Details

Tried all browsers and in regular and private mode.

Restarted backend and UI.

Reinstalled Lemmy and Lemmy-ui.

I'm not sure if it is the expected behavior, but I get a JSON error popup 2 times on the bottom left corner of the browser window in dark red.
