Expected result

The use of Date.prototype.getTime in the code below should be valid without any warning:

['2020-02-02'].map(n => new Date(n).getTime()); // no warning or fix is needed

Actual result

The nursery/useDateNow incorrectly flags the code below as warning due to the use of Date.prototype.getTime:

['2020-02-02'].map(n => new Date(n).getTime()); // Use Date.now() instead of new Date().getTime.

// after unsafe fix it becomes `['2020-02-02'].map((_n) => Date.now());` which is totally incorrect
