Fix E2E test output

[chatton]

Summary of Bug

Since #2064 was merged, the E2E test output only displays all at once after the test has run. I believe this has something to do with the fact that e2e tests are now in separate packages.

Previously, all e2e tests were in one e2e package and so go test was testing a single package. Now go test is testing multiple packages but filtering out all but the relevant one.

Expected Behaviour

Test logs are displayed as the test is running

Steps to Reproduce

Run any e2e test
