Allow Token/Basic auth on raw paths (#15987)

It appears that people have been using token authentication to navigate to raw paths
and recent changes have broken this. Whilst ideally these paths would not be being used
like this - it was not the intention to be a breaking change.

This PR restores access to these paths.

Fix #13772
