Base directory is hardcoded for init script

I'm writing an adapter around Migratus for an internal task runner. I'd like to write tests for it, and I'd like those tests to use a suite of migrations in my project's test_resources directory. I see there is a :parent-migration-dir option which controls where Migratus looks for the migrations directory, and this project's own tests use that option to run test migrations. The init function, however, does not respect this setting; it always looks in resources.
