A customer identified an issue trying to run Jaccard. In MG calls they were seeing failed memory allocation calls.
While computing get_two_hop_neighbors, vertices were being shuffled incorrectly in the C API, so we were getting vertices processed on the wrong GPU, resulting in out-of-bounds memory references.
Moved the shuffle before renumbering, which puts vertices to be on proper GPU
Closes #3746
