Inspired by laravel/scout@4.0...5.0#diff-f2faa85f27580a9b67d73a8a273bfef1 / laravel/scout@9f06b9c

* Remove PHP5 as laravel/scout^5 / laravel5.6 also removed it

Removed count function. Fixes #80 (#84)

Since php 7.2, count a number will generate a warning. Because
$results['hits']['total'] is a number we can just compare it to zero.

`if ($results['hits']['total'] === 0)`
