Problem/Motivation
We have a deprecation message warning in Drupal\Core\Database\Query\Select::__construct() when the parameter $alias is not null or not a string.
Proposed resolution
Replace the deprecation message for the $alias parameter in Drupal\Core\Database\Query\Select::__construct() with a InvalidArgumentException
