The initial verification of an OTP configured in FreeOTP fails.
Steps to reproduce:
* Edit `plugins/kolab_2fa/lib/Kolab2FA/Storage/Base.php` to not require non-existent `\Kolab2FA\Log`, as per T595,
* Edit `plugins/kolab_2fa/kolab_2fa.php` to not set the logger to non-existent `\Kolab2FA\Log\RcubeLogger` (also T595),
* Scratch the database (see T602),
* Login as a email@example.com,
* Attempt to add/configure a FreeOTP token.
