What happened?

The current method for query input parsing on CassandraIO assumes such query necessarily comes with a 'where' clause, which leads to an invalid resulting statement when this is not the case.

Example of the current behavior:

Input query:

select partition_col, other_col from keyspace.table

Resulting invalid query:

select partition_col, other_col from keyspace.table AND token(partition_col) >= ? and token(partition_col) < ?

Resulting error:

SyntaxException: [...] mismatched input 'AND' expecting EOF (..., other_col from keyspace.table [AND]...)
