* Check RowsAffected when applying DML events to get more accurate statistics
Addresses #600.
When applying a DML event, check the RowsAffected on the `Result`
struct. Since all DML event queries are point queries, this will only
ever be 0 or 1. The applier then takes this value and multiplies by
the `rowsDelta` of the event, resulting in a properly-signed, accurate
row delta to use in the statistics.
If an error occurs here, log it, but do not surface this as an
actual error .. simply assume the DML affected a row and move on. It
will be inaccurate, but this is already the case.
* Fix import
* update wording to warning log message
