Ah it looks like this is the case for standalone apps, but it's not the
case for sub-apps generated inside an umbrella project. That is, if I
change the config in one of my sub-apps then recompilation will not happen
and running `mix test` will not reflect changes to the sub-app's configs.
I'm guessing that the entire umbrella project shares the same build files
and the umbrella project only recompiles based on changes in the top-level
configs (even though the umbrella app seems to be reading the sub-app's
configs when it does compile)
