Allow searching for material samples using higher classification names present in determinations

[dshorthouse]

As in the subject. We can presently search for determination.scientificName and determination.verbatimScientificName held in organism, but it would be additionally useful to be able to search for any name drawn-in from the GlobalNames external service (or created via migration) & present in determination: [{ scientificNameDetails: { classificationPath: '###'}]. The separator will need to be honoured in this classificationPath, split, and then each name held here made searchable.
