customer_message.errors is always true on commit

{% if customer_message.errors %} will always be true, so that example is incorrect. It works only because of different success/error callbacks.

So the temporary solution is to use

  {% capture err %}{{ customer_message.errors | first}}{% endcapture %}
  {% if err != "" %}

that doesn't seem right
