Ensure `StatementCache#execute` never raises `RangeError`
Since 31ffbf8d, finder methods no longer raise `RangeError`. So `StatementCache#execute` is the only place to raise the exception for finder queries. `StatementCache` is used for simple equality queries in the codebase. This means that if `StatementCache#execute` raises `RangeError`, the result could always be regarded as empty. So `StatementCache#execute` just return nil in that range error case, and treat that as empty in the caller side, then we can avoid catching the exception in much places.
