Branch 1.2 and PHP 7.2

[aescarcha]

Hi, I'm trying to upgrade an old project of mine to PHP 7.2, I found that there's a couple of issues with the captchas when running Laravel 4.2 and laravel-authentication-acl 1.2, it's

ErrorException: count(): Parameter must be an array or an object that implements Countable 

/var/www/myproject/workbench/aescarcha/mypackage/vendor/gregwar/captcha/Gregwar/Captcha/CaptchaBuilder.php:326

and

ErrorException: imagejpeg() expects parameter 1 to be resource, null given 

/var/www/myproejct/workbench/aescarcha/mypackage/vendor/gregwar/captcha/Gregwar/Captcha/CaptchaBuilder.php:558

At least the first is already fixed in this issue, I know Laravel 4.2 is very old but, could you update the dependency? Thanks!

I cannot actively work on this but any PR to fix the issue is appreciated
