Incorrect checking for PHP7 return types on multi-line function declartions

[syrm]

Hello,

With a code like that :

    public function driverIsConnectedWithIdentifierForQuery(
        DriverInterface $driver,
        $identifier,
        QueryInterface $query
    ): ConnectionPool {

PHPCS : There must be a single space between the closing parenthesis and the opening brace of a multi-line function declaration
