Fail to build database when multiple antiSMASH version result are present

[matinnuhamunada]

The command bgcflow build database fails when there are multiple antiSMASH versions in the data_warehouse. This is because dbt will fetch all parquet of the different versions and then fail the test because there are duplicates of the ids (genome_id, region_id, etc). The dirty fix is to clean up the processed folder to only have result from 1 antiSMASH version. Or improve the DBT schema to only use the latest version of the result.
