Using the ui_patterns view style can error out when there is a single result row

FYI, our workaround in our pattern is wrapping "grid_items" if it isn't a sequence.

<ul class="{{ component ~ '__grid-items' }} {{ component ~ '__grid-items--' ~ variant }}">
  {% set grid_items = grid_items and grid_items is not sequence ? [grid_items] : grid_items %}
  {% for grid_item in grid_items %}
    <li class="{{ component ~ '__grid-item' }}">{{ grid_item }}</li>
  {% endfor %}
</ul>

I updated the check for multi value slots.
