Uncaught TypeError: Cannot read properties of null (reading 'bypass')

Problem/Motivation

Javascript error in tarteaucitron.js when tarteaucitron.user is null:

Uncaught TypeError: Cannot read properties of null (reading 'bypass')

Related code causing the crash (line 868):

        // allow by default for non EU
        if (isResponded === false && tarteaucitron.user.bypass === true) {

Proposed resolution

We should create an empty user if not provided by drupalSettings.
