theme.yml: disable logo div when logo is set to 'false'

[sablonier]

If in theme.yml logo image is set to 'false' div remains and gives 'empty space' .
In partials/_navbar.twig check should be changed to something like {% if theme.logo != 'false' %} <img src="{{ asset(theme.logo, 'theme') }}" width="33" height="33" class="d-inline-block align-top" alt="">. Maybe also width and height could be theme.yml parameters.
