When changing the text of a message template via the text is missing

[RoySegall]

During DDD 2017 I started to work on the tests of Message UI. I found when settigng the text of the message template entity the text is being removed:

    $messageTemplate = MessageTemplate::create(['text' => ['bar'], 'template' => 'bar']);
    $messageTemplate->save();

    $template = MessageTemplate::load('bar');
    dpm($template->getText());
    $template->set('text', ['b']);
    $template->save();
    dpm($template->getText());

Will output for the first text printing:

Array
(
[0] => stdClass Object
(
[CLASS] => Drupal\Core\Render\Markup
[string] => asdasd
)
)

But after saving:

Array
(
)

I'm looking on the tests and it seems that the proper way to set the text is:

    $this->messageTemplate->set('text', [
      [
        'value' => 'foo [fake:token] and [message:author:name]',
        'format' => filter_default_format(),
      ],
    ]);

Rather than

$template->set('text', ['b']);

@amitaibu @jhedstrom If that the case - shouldn't we have an API function to do that for us?

We have a test helper method in MessageTemplateCreateTrait::createMessageTemplate that makes it easier to set text without a format. I suppose we could add an api method that calls out to filter_default_format if no format is passed in...
