Fix provenance

[shyamd]

Fixes a number of bugs in the provenance builder

• Ensures structures are compared rather than SNLs
• returns to the normal species comparator as OrderDisorder is taking forever
• serializes string History descriptions back to dictionaries
• fix a "feature" with pybtex that was causing duplicate references to fail rather than just deduplicate
