In ed6c9d154591b620e3347a417173b373f4738be7, we started flushing
Redis's database at the end of each test. However, we had something like
this:
```
config.after(:each, type: :system) { teardown system test stuff }
config.after(:each) { # flush redis }
```
When stuff was defined in this order, flushing redis was called before
the teardown of system test. Instead we have to switch the order around
which is what this commit does.
