All key quals are given (including optional) if required key quals are missing in query

[cbruno10]

Describe the bug
For instance, if I have:

func tableAwsCloudtrailEventsListKeyColumns() []*plugin.KeyColumn {
	return []*plugin.KeyColumn{
		// CloudWatch fields
		{Name: "log_group_name"},
		{Name: "log_stream_name", Require: plugin.Optional},
		{Name: "filter", Require: plugin.Optional},
		{Name: "region", Require: plugin.Optional},
		{Name: "timestamp", Operators: []string{">", ">=", "=", "<", "<="}, Require: plugin.Optional},
		// event fields
		{Name: "event_category", Require: plugin.Optional},
		{Name: "event_id", Require: plugin.Optional},
		{Name: "aws_region", Require: plugin.Optional},
		{Name: "source_ip_address", Require: plugin.Optional},
		{Name: "error_code", Require: plugin.Optional},
		{Name: "event_name", Require: plugin.Optional},
		{Name: "read_only", Require: plugin.Optional},
		{Name: "username", Require: plugin.Optional},
		{Name: "user_type", Require: plugin.Optional},
		{Name: "event_source", Require: plugin.Optional},
		{Name: "access_key_id", Require: plugin.Optional},
	}
}

If I run a query not giving log_group_name but pass an optional key qual, I get:

> select * from aws_cloudtrail_trail_event where region = 'us-east-1';
Error: rpc error: code = Internal desc = 'List' call is missing required quals:
column:'log_group_name' operator: =
column:'log_stream_name' operator: =
column:'filter' operator: =
column:'timestamp' operators: >,>=,=,<,<=
column:'event_category' operator: =
column:'event_id' operator: =
column:'aws_region' operator: =
column:'source_ip_address' operator: =
column:'error_code' operator: =
column:'event_name' operator: =
column:'read_only' operator: =
column:'username' operator: =
column:'user_type' operator: =
column:'event_source' operator: =
column:'access_key_id' operator: =

From this message, it seems like all of these are required, not just log_group_name
