ThreadNet tests: make test output less verbose (#1685)

This small change makes the output of passing ThreadNet tests less
verbose by allowing to use `tasty`'s `--hide-successes` CLI option.

With this change, the output of the following test invocation:

```
cabal test -O0 cardano-test --test-options '--hide-successes -p "$2==\"AllegraMary ThreadNet\" && $3==\"simple convergence\""'
```

is still very verbose, but, in my opinion, is relatively readable:

1 of 1 test suites (1 of 1 test cases) passed.
```
</details>

without the change, the output contains a series of long lines that make
the output much more difficult to comprehend. When I see the output, I
have a feeling that there's something wrong with this test, even though
it is passing. This is especially annoying in CI output, when some other
tests are actually failing.
