This updates tests for `AVA` 19.0.0+. `AVA` 0.18.0 has a breaking change which changes the current working directory for tests. As a result, we need to change 'resources' -> 'test/resources' (and similar path changes). `AVA` 0.19.0 has a breaking change that all tests must run at least one assert. This breaking change was already resolved by #746, so no change was necessary in this PR. This updates to `AVA` 0.21.0, since there are no other breaking changes.
