SELECT 1
FORMAT JSON

{
	"meta":
	[
		{
			"name": "1",
			"type": "UInt8"
		}
	],

	"data":
	[

The issue appears only in interactive mode. In non-interactive mode clickhouse-client produces the correct output:

```
# clickhouse-client -q 'select 1 format JSON'
{
	"meta":
	[
		{
			"name": "1",
			"type": "UInt8"
		}
	],

	"statistics":

		"rows_read": 1,

}
