tests/dedo.go: Normalize tests

- hack extra `os.Remove()` calls to avoid leaving temporary files around;
- try using temporary directories that usually live in RAM;
- disable broken tests;
- stop printing to stdout/stderr;
- decrease test constants to make slow tests bearable*.

(*): tests are bearable in RAM (~5s) or on SSDs (~10s).  HDDs are still too slow
for them (~2m).
