Handling edge cases for the SequenceSymmetricAnnealer
SequenceSymmetricAnnealer started out as a hack and slowly matured into a feature that was merged to master in #4117 and #4260. Some edge-case handling was missed during the de-hackifying process.
The branch name is misleading. This is not Thanh's bug - this is my bug that Thanh found.
Thanks Rocco for the review!
