Fix unit test runner and failing tests

[pcalcado]

The canonical test command used in our .travis.yml passes:

$ go test -v ./...  --run "^(integration_test)" >/dev/null; echo $?
0

But I realised that even if I make a test fail on purpose, it always passes. So I've tried running without the --run "^(integration_test)" bit, and now this hangs forever:

$ go test -v ./...   >/dev/null; echo $?

So in commit e043adf I've changed our travis file to the command above. In commit a4db27c I;'ve also made the integration tests only CONDUIT_INTEGRATION_TESTS_ENABLED, removing the need for the flag on go test.

Now it still hangs, but before hanging it shows us that another test was broken and has never been reported as such:

$ go test ./...

So on commit 1c5adc6 I've fixed the bug that was causing the test to hang, and now we have a broken build, as it should the case since forever. Running locally you get this:

$ go test -v ./...   >/dev/null; echo $?
1

Subsequent commits fix tests that had been failing for a while and we didn't know about because of the problems stated above. After that we're back to a good state:

$ go test -v ./...   >/dev/null; echo $?
0

⭐️ Wow, good sleuthing, and thanks for cleaning this all up.

TIOLI -- you could move this up with the rest of the consts at the top of this file.

Typo here: presentn => present

⭐️ Great, thanks for updating. I think this just needs a master merge, and it should be good to go.
