constant: No text for TestConstantExpression defined

[Miras4207]

It seems this plugin does handle constant function correctly.

The following example code:

{% if post.status is constant('Post::PUBLISHED') %}
    the status attribute is exactly the same as Post::PUBLISHED
{% endif %}

is incorrectly changed to:

{% if post.status is (Post::PUBLISHED) %}
    the status attribute is exactly the same as Post::PUBLISHED
{% endif %}

Prettier command outputs the following message:

TestExpression: No text for TestConstantExpression defined

Versions used:
Prettier 2.5.1
prettier-plugin-twig-melody 0.4.6

Any help with this topic would be much appreciated.
Thank you.
