Being invited to a Space via URL: Fix Unhappy path Spinner (with Join button)

Your use case

During Community Testing session October 5, 2021 a user encountered the following:

"By URL - as a new user: When I don't create a new account (press X at top right), the Space keeps sitting there with a spinner, which is kinda not optimal. I think making the "join" button reappear would make sense."

To recreate, click [X] at step 6:

1. [User 1] Right click on space in left panel and "Invite people"
2. [User 1] Copy link and share with another user who doesn’t have an account (e.g. open it in a private browsing session or in another web browser)
3. [Unregistered user 2] Another account clicks the link to join
   -> See matrix.to page with “Continue”
4. Click “Continue” and then continue with Element in your browser (you should see two more pages on element.to)
   -> app.element.io loads
5. Replace “app” in the URL with “staging”
   -> Account appears as "Guest"
6. [Unregistered user 2] Click on “Join”
   -> See “sign in or create account” dialog
7. [Unregistered user 2] Create new account (see test case for creating new account
   On account creation completion, now registered user 2 should be a member of the space
