Symfony version(s) affected: 4.1 and prior (since 6 years i think)

Description
When the translation is disabled (and the translator component not even install) and use a ChoiceType input in your form, we get the following exception :
Uncaught PHP Exception InvalidArgumentException: "The helper "translator" is not defined."

How to reproduce

• Unistall translator component
• Disable translation in the framework.yaml
• Create a form with ChoiceType input
• Set the choice_translation_domain to false

Possible Solution
In the file choice_widget_options.html.php on line 3, it would be nice to add a test on the existence of the translator component. Or check if the enable translator option in conf is set to false.
