"Addresses" Portal Menu Item is non-functional

[trustedcomputer]

Information about bug

The Portal Menu Item "Addresses" doesn't work at all:

1. It displays a non-working link to unauthenticated users at /portal, the guest can click it but then is denied access anyway
2. A logged in customer on portal can click on the portal link, but they are redirected to the wrong URL /addresses and get a 500 error with a traceback
3. A logged in customer can manually type in the correct URL /address and enter a new address or edit one of their previously entered addresses but at the end, they are redirected to the wrong URL /addresses resulting in 500 error

@DipenFrappe this issue isn't resolved yet, neither #52711 nor #52712 have been merged, and @mihir-kandoi and I are still working on them.
