Merge branch 'fix-lfs-ci-fetch' into 'master'

Fix LFS CI fetch

## What does this MR do?
Fixes LFS fetching for CI objects that were kind of broken.

## Why was this MR needed?
This also refactors LFS tests to be a blackbox tests instead of whitebox tests. Actually testing GrackAuth instead of LFSRouter.
