Restore default locationID selection to bulk import

[holmbergius]

Restores auto-selection of the bulk import-specific locations IDs, properly scoping ID requests as a result when they are sent from the bulk import's page. The lack of this has caused overscoped matching in Wildbook and much slower, very large jobs in WBIA.

Changes

• Allows for multi-selection of the generated HTML for the locationID selector based on a passed in list of 0 or more location IDs. Retains single locationID selection.
• Restores scoped location ID selection by default to the location ID pulldown for matching on the bulk import page. Multiple locationIDs in the bulk import Encounters result in each locationID being included in the default scope
