Do not filter on translation table in GO.py when retrieving ensembl d…

…ump. (#386)

As far as I'm aware the translation table was previously used because it was needed for the ID mapping.

If we wanted to restricted GO categories by gene type, this would be better done via biotypes.

But probably best to take all GO categories here regardless of gene biotype and to instead encourage people to filter downstream.
