Great cleanup!!!

* @param store who we scan
* @param scanners ancillary scanners
* @param smallestReadPoint the readPoint that we should use for tracking
versions
* @param dropDeletesFromRow The inclusive left bound of the range; can be
EMPTY_START_ROW.
* @param dropDeletesToRow The exclusive right bound of the range; can be
EMPTY_END_ROW.
