PHP 8 - Method ReflectionParameter::getClass() is deprecated

[kocsismate]

Hi Matthieu,

PHP 8 deprecates the ReflectionParameter::getClass() method, and suggests the usage of ReflectionParameter::getType(). This causes problems (and a slight performance penalty) to PHP-DI.

There are some commits in PHP-DI/PHP-DI#726 that solve this in PHP-DI, we should apply the same logic here (if anyone is up for a PR).

I started working on #20 but PHP 8 support is harder than I anticipated.

Thank you @mnapoli for the fix! I didn't get around implementing this, because I was too busy with PHP 8 before the RCs.
