timers: call destroy on interval error
When an interval callback throws an error, the destroy
hook is never called due to a faulty if condition.

Was left over from another test for async hooks. It's not a very helpful comment to be honest. Removing.

setInterval(common.mustCall(ontimeout), TIMEOUT);
const as = hooks.activitiesOfTypes('Timeout');
assert.strictEqual(as.length, 1);
const t1 = as[0];
assert.strictEqual(t1.type, 'Timeout');
assert.strictEqual(typeof t1.uid, 'number');
assert.strictEqual(typeof t1.triggerAsyncId, 'number');
checkInvocations(t1, { init: 1 }, 't1: when timer installed');

function ontimeout() {
checkInvocations(t1, { init: 1, before: 1 }, 't1: when first timer fired');

throw new Error('setInterval Error');
}

process.on('uncaughtException', common.mustCall((err) => {
assert(err.message, 'setInterval Error');

This seems to miss .strictEqual.

}));

process.on('exit', () => {
hooks.disable();
hooks.sanityCheck('Timeout');

checkInvocations(t1, { init: 1, before: 1, after: 1, destroy: 1 },
't1: when process exits');
});
