BCO Extension Domain And IO Domain errors

Describe the bug
ARGOS_000022 corresponds to the Pond Team assemblyQC table (Galaxy)
ARG_000001 Corresponds to Pond Team Wuhan Fasta (Galaxy)

It seems like in both of these issues, the 'filename' field in the BCO are written out as steps rather than a file name with a media type. I believe The URI warning is occurring because the script is looking for a file name referenced in the URI - but the filename field is text, there isn't a reference to an actual file, and this isn't represented in the URI.

Long term this should be addressed in Galaxy and the BCO converter. Short term - these fields could be edited or removed to be compliant to the BCO standards. However, being that they are WARNINGS and not FATAL, it might be okay for now.
