Reformatted arrays in test files

[jorgsowa]

Reformats arrays in test cases using PHP-CS Fixer and following rules:

• "whitespace_after_comma_in_array": {"ensure_single_space": true},
• "array_syntax": true,
• "trailing_comma_in_multiline": true,
• "method_argument_space": true

Per comment in: #13128 (comment)

I don't think we should do that. In #13128 (comment), I was only referring to the two tests with the deeply nested indentation (which this doesn't seem to address).

[jorgsowa]

Sure. I will close it then, although I think some of the test snippets are ugly written and should be reformatted one day.

Yeah, I don't disagree that the formatting is objectively better. The problem is that it creates more merge conflicts, which sadly is not something that will ever change. This is also why we cannot automate the formatting of the C source code.
