Azat Khuzhin 3ce4844d4b Properly cancel the query after client format error
In case of format error (i.e. select 2 format Template settings
format_template_row='/dev/null') the client will reset the connection,
since it will not expect Data blocks.

To fix this, catch this client error and properly cancel the query. This
should also fix query hang checks (the one that executed after each test).

v2: use getCurrentExceptionMessage()/getCurrentExceptionCode()
