[SPARK-49039][UI] Reset checkbox when executor metrics are loaded in …

…the Stages tab

### What changes were proposed in this pull request?
This PR aims to reset checkbox when executor metrics are loaded in the Stages tab.

### Why are the changes needed?
The variable `executorSummaryTableSelector` in the `reselectCheckboxesBasedOnTaskTableState` function may not be initialized, which results in inconsistent UI display.

Sometimes `allexecutors` api calls are slow, which causes `executorSummaryTableSelector` to be initialized lazily.
```js
$.getJSON(createRESTEndPointForExecutorsPage(appId),
```
