The following lines expect each unit has property "-1" and "1"
```
const expected = unit in exceptions
? [exceptions[unit]["1"], exceptions[unit]["0"], exceptions[unit]["0"], exceptions[unit]["-1"]]
: [`in 1 ${unit}`, `in 0 ${unit}s`, `0 ${unit}s ago`, `1 ${unit} ago`];
```
The specification was changed to remove the useGrouping option in
<https://github.com/tc39/proposal-intl-relative-time/pull/81>.
The change to remove the minimumIntegerDigits option in that PR was already
taken into account; this commit also removes the reference to the issue.
This also removes some commented-out code that was left in by accident.
