#1955 SELECT .. FETCHPLAN doesn't work in binary protocol

It fixes #1955. After change, FETCHPLAN works with binary protocol on two levels
- COMMAND level - defined in COMMAND payload
- SQL SELECT with FETCHPLAN clause

If both are defined SQL FETCHPLAN overrides COMMAND fetch plan.

Since now
SELECT FROM V WHERE name="HEY BO DIDDLEY" FETCHPLAN "*:1"
returns via binary protocol expected
