[edge] MAAS sends to network discovery on login

[webteam-app]

Bug originally filed by stgraber at https://bugs.launchpad.net/bugs/1939032

Recently on latest/edge, MAAS has started sending everyone to /MAAS/r/dashboard after login.
This seems reasonable in theory except that instead of being some kind of dashboard primarily showing the machine list as one would expect, it's instead showing the network discovery page.

This is made a bit worse because in my setup, network discovery is disabled, so that results in everyone logging into my MAAS getting an error/warning about network discovery being disabled and then having to figure out that they need to hit the machine tab to get back to what they want :)

It looks like this has been inadvertently fixed as of this commit in MAAS, in which a separate bug regarding setting cookies was fixed (specifically this line of a PR). At least in my own testing, the issue is present before that commit and not present after that commit, so I will assume that nothing more needs to be done. Please re-open if you're still running into this issue on the edge snap.
