Datalabeling tests are broken

[kurtisvg]

Data labeling test are broken - likely a race condition when using a single project.

See #2642

@kurtisvg Do you want to take this or should I? I'm happy to investigate but I saw that you'd done the change referenced in the commit and I was auto-assigned.

[kurtisvg]

Happy to let you take over if you are willing - I was only attempting to update the snippets to use the test endpoint, which is how I discovered the tests were broken.

[gguuss]

I'll take a look, currently waiting on a few other work items.

Anecdotally the tests are passing under nox in Python 2.7 and when directly invoked from Python 3.7 with pytest.

[gguuss]

As mentioned in the bug this does seem to be specific to running the tests in parallel.

Repro in #2662

[gguuss]

That branch got really messy, it appears to be a race condition in the teardown.

[gguuss]

Progress in #2665 I have serialized the tests in that branch to try and determine the ordering of the build-up / tear down / timing that is causing the problem. Still failing though.

[gguuss]

I was unable to resolve this, assigning to @kurtisvg

@kurtisvg PTAL

Closing in favor of buildcop issues.
