Run tests in async mode where applicable (#2542)

* Set pg pool size for MIX_ENV=test

* Include slow tests in CI run

* Exclude slow tests by default

* Mark tests slow/async where applicable

* Restructure captcha mocks

* Revert async where env is relied upon

* Add --max-failures=1 to CI run

* Set warnings as errors

* Disable async where various mocks are used

* Revert "Disable async where various mocks are used"

This reverts commit 2446b72a29.

* Disable async for test using vcr
