Route name of hidden projects contains errors when unauthenticated

[hudson-newey]

Describe the bug

When unauthenticated (e.g. sending a link through teams) the page title cannot fetch the project name, so therefore it breaks and shows "Ecosounds | ProjectsProject"

To Reproduce
Steps to reproduce the behavior:

1. Send a link to a private project
2. Observe that the site title in the card preview is broken

Expected behavior

I expect that the unauthenticated title would look something like "Ecosounds | Project"
