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

Browse source 
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
