    1172: Resolve visibility paths  r=CohenArthur a=CohenArthur
    
    This tackles the remaining issues in #1158. ~~It also contains the commit from #1168 so you should wait for bors to merge that before reviewing it :D~~ done
    
    The paths get resolved but their `NodeId`s are not used in the privacy visibility resolver yet.
    
    Closes #1158
