Fix OIDC logins silently failing when switching accounts

[770grappenmaker]

Fix OIDC logins in the account switcher failing due to the router ignoring login attempts. Closes #40 and probably more related issues.

Description

The router only lets you visit /home or the like if addAccount is unset, but this did not account for loginToken. Now, if loginToken is set, you visit the /login/server route instead of being redirected to /home, allowing the account switcher to work as intended.

Fixes #40
Fixes #284

Perhaps an additional check should be done whether this concerns the /login endpoint
