Invalid verification token results in internal server error

[baranyildirim]

Description

By default, the handler for /api/auth/verify/{token} returns an internal server error (500) if the token cannot be found.

To Reproduce

Use default SaaS template.
Make a GET request like:

curl localhost:9000/api/auth/verify/asdasdkad

Expected Behavior

Shouldn't this be a bad request (400)?
