Loading isn't hide

Sometimes <IonLoading> is showed even after set:
```
setShowLoading(false);
setData(data.rounds);
```
To reproduce: refresh page few times in browser.

To fix it try to add duration={10}:
```
<IonLoading
            isOpen={showLoading}
            onDidDismiss={() => setShowLoading(false)}
            message={'Loading...'}
            duration={10}
          />
```
