Discovery of tests in identically-named suites in the same file only works for the last suite#65

``` 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
