REFACTOR: Test Memory Usage Fixes (#7769)

* Calling `Discourse.reset()` creates a new container
We should run our de-initializers only after acceptance tests,
since initializers are not run outside of acceptance tests anyway,
and the container at this point can be passed properly to the
`teardown()` method.

* Remove `Discourse.reset` from tests
This would cause a new container to be created which leaks many objects.

* `updateCurrentUser` is more accurate than `replaceCurrentUser`
