Update hasRecord() PHPDoc type hint, reflecting the actual method implementation

[sasezaki]

I found this with PHPStan level 5

vendor/bin/phpstan analyse --level=5 src
 3/3 [▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓] 100%

  51     Call to function is_string() with array will always evaluate to false.
         🪪  function.impossibleType
         💡 Because the type is coming from a PHPDoc, you can turn off this check by setting treatPhpDocTypesAsCertain: false in your phpstan.neon.
