https://jira.mongodb.org/browse/PHPLIB-494
This fixes a few validation errors where it is possible to use
nullas a valid value for an option, resulting in undefined behaviour. All other options that have a default value are directly checked for their type, without anissetcheck to guard against a missing option since it should always be present due to the array union.
