Increase data directory test coverage * Adds retro-coverage for #4361 * Verifies open issues #4138, #3890, #4366, 4083 * Removes test reliance on the very code it is testing (hugo/parser package). Expected results are now all built manually / are more precise. Tests can run against different versions (no linkage errs)
