Php-cs-fixer: Fixer that replaces call_user_func_array() with argument unpacking

[julienfalque]

e.g.:

-call_user_func_array($callable, $arguments);
+$callable(...$arguments);

[dmvdbrugge]

Just a note for whoever picks this up, this will break:

-call_user_func_array($this->callable, $arguments);
+$this->callable(...$arguments);

Here's a workaround:

-call_user_func_array($this->callable, $arguments);
+($this->callable)(...$arguments);

I would want the same for call_user_func() as well.

- call_user_func($callable, $a, $b, $c);
+ $callable($a, $b, $c);
