Cast total results to int before returning

[craigpotter]

This PR forces the results of the totalResults method on the paginator to return an int.

The method already has return type of int however some API don't follow conventions and actually supply this value as a string.

{
	"ResultInfo": {
		"page": "1",
		"per_page": "20",
		"total_count": "47"
	},
}

Without this PR, this results in an error due to a mismatch in the return type.

• Change in totalResults() method
  The method now makes sure that the $total variable is always an integer. This improves the code reliability and ensures smooth functioning. Keep up the great work! 😃
