Incorrect Redirect After Sign-Up from Course Invite

Description:
When an unregistered user opens a course invitation link, they are prompted to log in or sign up. After completing sign-up, the user is redirected to the marketplace instead of the invitation page. To accept the invitation, the user must reopen the invite link after signing in.

Steps to Reproduce:

1. Navigate to the Spaces screen.

2. Open a course.

3. Click on the Add New User button.

4. Select Invite via Link.

5. Generate a new link for the Attendant role.

6. Open a new incognito tab and paste the link generated in step 5.

7. Sign up using a new/temporary email.

Expected Behavior:
After signing up, the user should be redirected back to the course invitation page to accept the invite.

Actual Behavior:
After signing up, the user is redirected to the marketplace page instead.
