Null values and empty arrays being populated to Database by workflow automation

[mbthornton-lbl]

TRiP records in the production database have null values and empty arrays for workflows - for example:

nmdc:wfmgan-11-4sc85678.1
that record is from two days ago but has a key for gold_analysis_project_identifiers and has_failure_categorization, both with empty arrays

Closing b/c this is an issue on the runtime side, will make a new ticket in nmdc-runtime.
