FormHelper :: control() should not default to FALSE values

[starlocke]

This is a (multiple allowed):

• [x] bug

• [ ] enhancement

• [ ] question

• CakePHP Version: 3.8

• Plugin Version/Branch: dev-master

A bug was found

• Vanilla CakePHP 3.8 installed.
• Vanilla "tutorial" demo tables created.
• "cake bake all articles"
• Hey, the "required" decorators work just fine.

In contrast:

• A project migrated from CakePHP 3.4 -> 3.7, and even 3.8 suddenly lost the "required" decorators (asterisk, bold).

A root cause was found and patch created

... See pull request.
