Discovery of tests in identically-named suites in the same file only works for the last suite

```
describe("math", () => {
it("addition", async () => {
console.log("some log");
strictEqual(1 + 1, 2);
});
});

describe("math", () => {
it(`subtraction`, async () => {
process.stdout.write("another log");
strictEqual(1 - 1, 0);
});
});
```

**NOK**: Only math > subtraction will be discovered
