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.
