Try disabling git fetch filters for `Test` workflow

[bduffany]

I am seeing git fetches take a long time after force-pushing to a branch (about 45s - 1 minute). The branch doesn't contain a lot of changes so this is pretty surprising. Try disabling --filter=blob:none to see if that helps (this fixed slow git fetches for a customer so I figure it's worth trying ourselves)
