Update microbial genes to use chromosomes instead of Refseq Genome ID

[stuppie]

Currently microbial genes use the Refseq Genome ID as a qualifier.

Changes to be made:

1. Add Genbank Assembly Accessions to strain items (e.g. https://www.wikidata.org/wiki/Q20800254#P4333)
2. Create chromosome items for each strain (e.g. https://www.ncbi.nlm.nih.gov/nuccore/NC_010287.1)
3. Change qualifiers from "Refseq Genome ID" -> ID, to "Chromosome" -> chromosome item

Part 1 Mostly done already: https://github.com/stuppie/wikidatacon_wdi_demo/blob/master/demo.ipynb But need to check to make sure all the reference genomes are covered.

Part 2 To do. Data source: https://www.ncbi.nlm.nih.gov/genome/browse/reference/

Part 3 To do. Requires bot update
