test authentication

[casperdcl]

Add authentication test

• revert @LoadAuth removal once proved that new test fails
  • confirm new test passes
• continues files: fix auth for GetContentFile #32
• prevents file.GetContentFile(...) throws AttributeError as of version 1.4.11 #31

On a related note... the tests are not designed to run concurrently.

• one job from the PR build failed at the same time as a job from the branch build because they interfered with each other
• tests are slow as they are not run in parallel

Really should fix this (e.g. timestamp filenames)

the only minor ask - let's name the test with some meaningful name and put some comment?

other tests are generic ... this one tests a pretty specific behavior.

agreed! let's create a ticket for this in this repo. Not sure we have capacity to do this now unfortunately, but will try to handle somewhere down the road. It's good that we have tests running at all.. Initial pydrive does not have them at all 🤷‍♂️
