Unable to bind list values using global type constants

Given the following table using a list

and the following prepared or bound insert statement to insert the list items

and creating the list object instance through the global type definition

The driver will throw an `InvalidArgumentException: Invalid value type` when binding the values using the ExecutionOptions and executing the statement; NOTE: Map and Set objects do not produce the exception.

A current workaround is to use either of the following syntaxes when creating a list object with v1.2.2 of the PHP driver:

• $list = new Cassandra\Collection(Cassandra\Type::varchar());

• $listtype = Cassandra\Type::Collection(Cassandra\Type::varchar());
  $list = $listtype->create();
