CLJS-2915: Tests fail if directory has a period (.) in the path

We replace the periods with hyphens. We then leverage the cond-> to selectively transform to underscores.

I coded this specific `replace` as char / char - which is different from the string / srting pattern used in the rest of the pipeline - as it feels simpler than the equivalent regex.
