Patch Target Data Row Duplication Bug

[O957]

This PR adds protection for situations where target data in one of the hubs is manually generated, before the scheduled run, and then the PR from the scheduled run is accidentally merged. Historically, accidentally merging the target data from the second PR duplicated the rows, which this PR prevents.

With slight revision, this PR could address #66. Can you revise so that it does?

Re: #152 (comment). Yes, sounds good.

Instead of this, could you just call dplyr::distinct before saving?
