new-keyword-redefinable causes Parse error: syntax error, unexpected token "->"

Thank you again for quickly fixing #126! I ran into a different problem after I tried 2.1.20 on my project.

Patchwork rewrites the following:

$test = new class(new TestClass()) {
};

as something like:

$test = new class\Patchwork\CallRerouting\getInstantiator(...)->instantiate() {
}

The spliceAllInstantiations() removes the parenthesis around (new TestClass()) and produces an invalid anonymous class declaration:

patchwork/src/CodeManipulation/Actions/RedefinitionOfNew.php

Lines 44 to 46 in dbe712f

    
           if (hasExtraParentheses($s, $new)) { 
        
               removeExtraParentheses($s, $new); 
        
           }

I believe the fix for this problem is to add T_CLASS to the list of exceptions in hasExtraParentheses() so I'll try to pen a PR with tests and that oneliner.

Thank you for fixing this! This is now part of version 2.1.21.

	if (hasExtraParentheses($s, $new)) {
	removeExtraParentheses($s, $new);
	}
