PHP7 has deprecated same-named functions as constructors

As per, http://php.net/manual/en/language.oop5.decon.php, "Old style
constructors are DEPRECATED in PHP 7.0, and will be removed in a future
version. You should always use __construct() in new code." The current
tests fail on PHP7.0 based installs due to the deprecation warnings.

Bump the minimum version of PHP to 5.0.0 where __construct support was
added.
