apply fix to get genome by specific keyword

[darefalola]

This PR applies a fix to the GetGenomesBySpecificKeyword gRPC method.
Downstream applications like Thoas that uses this method have been discovered to return incomplete results. This is because the last implementation of the method groups by assembly accession and sorts by release version and returns only the top release version.
This PR

• sorts by assembly accession
• group by the assembly accession
• sorts and groups by genome uuid
• if there is an integrated release in each group, it selects that and add it to the list
• if none it returns the latest partial release after sorting to the list
• it returns the combined list of genomes.
