fix(reporter): don't double-count tests

[lkipke]

Summary

Whoops, our Jest reporter was double-counting all non-failure tests.

These numbers are incremented elsewhere:

roca/src/reporter/JestReporter.ts

Lines 70 to 83 in 7176ce5

	parser.on("pass", (assert: Assert) => {
	this.currentResults.numPassingTests++;
	this.addNonFailureTestResult(assert, "passed");
	});
	parser.on("skip", (assert: Assert) => {
	this.currentResults.numTodoTests++;
	this.addNonFailureTestResult(assert, "skipped");
	});
	parser.on("todo", (assert: Assert) => {
	this.currentResults.numTodoTests++;
	this.addNonFailureTestResult(assert, "todo");
	});
