list function in prepareColumnsLIst in PHP 7

[chris-huffman]

Preconditions

1. Magento 2.0.7
2. PHP 7

Steps to reproduce

1. call prepareColumnsList() in Magento\Framework\DB\Helper line 199.

list($correlationName, $column, $alias) = $columnEntry;

Expected result

1. In PHP 7, calling list() starts with the left-most parameter (as stated in the php manual)

Actual result

1. The method still works, but the values for $correlationName and $alias are reversed and this could result in unexpected errors or confusion.
