If this tracker is ever used, won't you get NPEs because the listener bus
is null?
This basically means you're forcing every test to call
`configureBlacklistAndScheduler()` manually. So either remove this
initialization, or do this properly, and just call
`configureBlacklistAndScheduler()` for tests that need to override the default
config.
Since I don't see any test actually passing any custom config parameters,
might as well do the initialization properly here and get rid of
`configureBlacklistAndScheduler()` altogether.
