fix clickhouse (22.2.x) syntax errors

[vitrvvivs]

Error

{"error": "dao.CreateBlocks: code: 62, message: Cannot parse expression of type UInt64 here: ?, ?, ?, ?, ?, ?) VALUES : While executing ValuesBlockInputFormat"}

Cause

There is a space missing in constructed SQL INSERT statements. This became an parse error in a recent clickhouse update.

INSERT INTO x (...)VALUES (...);
should be
INSERT INTO x (...) VALUES (...);

Error

dao.New{error 26 0  clickhouse.New: newConnection: can`t make makeMigration: migration failed in line 0: --CREATE VIEW IF NOT EXISTS block_row_view AS
--select * from blocks ANY LEFT JOIN
--              (select blk_lvl, sum(tx_gas_price), sum(tx_fee), count()
--from transactions group by blk_lvl) as s USING blk_lvl ORDER BY blk_lvl DESC (details: code: 62, message: Empty query)}

Cause

There appears to have been a regression in the comment parsing, where the semicolon is parsed before the comment indicator. A comment including a semicolon becomes an empty statement.

[vitrvvivs]

Need the semicolon on the next line here, or else --public validators 134 rows get interpreted as an empty statement.
