In the process of trying to get tests running for individual gems I discovered that we try to resolve config/models/roles.yml relative to the current working directory. Which meant that I ended up putting what's essentially a test fixture at bullet_train-incoming_webhooks/config/models/roles.yml just to keep the tests happy.

Ideally we'd resolve that file relative to Rails.root (if we have Rails.root) and the test file could then live in bullet_train-incoming_webhooks/test/dummy/config/models/roles.yml.

Here are at least a couple of spots where that resolution takes place, there may be more:

It looks like there are a couple of spots in the roles gem where we tried to get the test suite to look at the right place, but those don't seem to work.
