use sync call for some api tests (#784)

a lot of the logging tests use async calls which was flaky with timings. there
are a couple left that use async, that we need to test, but this reduces the
probability of the flaky tests flaking to 2/5 instead of 5/5.

the behaviors we are testing here we should not be testing through the api,
for this exact reason, we can test a ton of this in the agent itself and not
have to rely on timings. not taking that here, but this fixes circle ci
flaking out for a few days.
