vscode.InputBox requires a title to show buttons

Shows buttons:
```typescript
		quickInput.title = 'Create Issue';
		quickInput.buttons = [
			{
				iconPath: {
					light: Resource.icons.light.Check,
					dark: Resource.icons.dark.Check
				},
				tooltip: 'Create Issue'
			}
		];
```
I have to include the title. If I leave it out, then buttons are not show.
