In this recent PR
https://github.com/Significant-Gravitas/AutoGPT/pull/10394/ the
navigation bar disappeared when logged out. A change was introduced
where the navigation bar does not show up if we don't have profile data
( _which we won't have when logged out_ ). This solves it + adds tests
covering the navigation bar in the logged out state.
