schemas/vegbien.sql: Renamed make_analytical_stem() back to make_analytical_db()

import_all: After starting geoscrub import in the background, wait for make commands to scroll by before starting NCBI import

mappings/VegCore-VegBIEN.csv: matched place: Also map verbatim place's geoscrub-related fields to the matched place, to link up with geoscrub's corresponding input place

import_all: Removed explicit by_col=1 from datasources that don't require it for proper import. (It will still be set if the user provides it on the command line.)

schemas/functions.sql: Removed duplicate previous version of _and() with fewer parameters

Regenerated vegbien.ERD exports

schemas/vegbien.sql: method: Made reference_id NOT NULL so the method table would automatically be datasource-scoped

mappings/VegCore-VegBIEN.csv: Renamed creator_ids to reference_id since they are now fkeys to reference

schemas/vegbien.sql: Made creator_ids an fkey to reference instead of party, so that datasources are stored separately from people and to allow adding reference-type metadata (URL, copyright, etc.) for each datasource

schemas/vegbien.sql: reference: Added unique index
