fix(cassandra): don't quote table name

[teenjuna]

Quoting of table name doesn't work in ScyllaDB:

cqlsh> select version, dirty from "usercounter.migrations" limit 1;
InvalidRequest: Error from server: code=2200 [Invalid query] message="No keyspace has been specified. USE a keyspace, or explicitly specify keyspace.tablename"

No quoting works :)

cqlsh> select version, dirty from usercounter.migrations limit 1;

 version | dirty
---------+-------
       1 | False

(1 rows)

I agree, same problem, up!
