Do not intentionally exclude any exercises from the Rust test suite (#985)

Per [slack](https://exercism-team.slack.com/archives/CR91YFNG3/p1602838984216700?thread_ts=1602837142.216600&cid=CR91YFNG3),
`tests.toml` has these semantics:

- a test whose uuid's value is `true` has been implemented in the test suite
- a test whose uuid's value is `false` has been rejected by the test suite
- a test whose uuid is missing from `tests.toml` is new, and has been neither
  approved nor rejected.

Before, the assumption was that no tests in the suite were rejected.
Therefore, it is not appropriate for any test to be labeled `false`.
Therefore, we comment out those lines by this script:

```bash
fd -uutf tests.toml -x \
    sed -E -i -e '/"?[-a-zA-Z0-9]+"? = false/ {
        i '\#' this test may not be in the suite but has not been intentionally rejected
        s/^/# /
    }'
```
