bulma (file, components): fix color fo icons: icons have no color specified anymore for a while, and use the color of parent elements. As they are often used in a `<a>` element (to work without javascript), they are often using a link color. This commit change a few icons to use a dark color instead.

<div id="list" class="container has-background-white px-1 py-1">
    {% include "list/view_generic.html" %}
</div>
