Use a consistent "country" name across USVI samples (both submitted to GenBank and not-yet)

[j23414]

Current Behavior

From slack:

the 'country' of those 26 is "Usvi" whereas the 5 samples originating from GenBank (e.g. accession "MW165884") have country of "Virgin Islands"

Expected behavior

That the country names would be consistent for both USVI that has been submitted to GenBank and not-yet-submitted to GenBank.

How to reproduce

Possible solution

From slack:

I think there are two options, either of which is better than the current approach which uses a mixture:

1. Change genbank to "USVI" during curate. From memory this was what Alli always used and so I think this is the intended country name. (It should be all-caps, but this isn't a dealbreaker.)
2. Change the spiked-in sequences to "Virgin Islands" to match GenBank. We'll need to add lat/longs for this as it's not in Augur's defaults and thus doesn't show in Auspice.
