Azat Khuzhin 7b4fcc5fc5 Read temporary tables on failure to avoid interpreting that bits as query 
Before this patch if the query failes (due to "Too many simultaneous
queries" for example) it will not read external tables info, and the
next request will interpret them as the query beginning at got:

  DB::Exception: Unknown packet 11861 from client

v2: reordering in the executeQuery() is not enough, since the query
    can fail in other places, before, i.e. quotas
v3: I cannot make non-intergration test (since there is no ability to
    receive "Unknown packet" via client, only from the server log),
    hence added one
