Updated stored procedure to account for LastModifiedBy

Previously, the `DeleteOrphanedLastModifiedAttributes` only accounted for `LastModified`, not `LastModifiedBy`—and, as such, would not get tripped if both the `LastModified` _and_ `LastModifiedBy` attributes were updated at the same time, even if no other attributes were updated. This resolves that issue, as a first step toward #88.
