[SPARK-31941][CORE] Replace SparkException to NoSuchElementException …

…for applicationInfo in AppStatusStore

### What changes were proposed in this pull request?
After SPARK-31632 SparkException is thrown from def applicationInfo
`def applicationInfo(): v1.ApplicationInfo = {
    try {
      // The ApplicationInfo may not be available when Spark is starting up.
      store.view(classOf[ApplicationInfoWrapper]).max(1).iterator().next().info
    } catch {
      case _: NoSuchElementException =>
        throw new SparkException("Failed to get the application information. " +
          "If you are starting up Spark, please wait a while until it's ready.")
    }
  }`

Where as the caller for this method def getSparkUser in Spark UI is not handling SparkException in the catch

`def getSparkUser: String = {
    try {
      Option(store.applicationInfo().attempts.head.sparkUser)
        .orElse(store.environmentInfo().systemProperties.toMap.get("user.name"))
        .getOrElse("<unknown>")
    } catch {
      case _: NoSuchElementException => "<unknown>"
    }
  }`

So On using this method (getSparkUser )we can get the application erred out.

As the part of this PR we will replace SparkException to NoSuchElementException for applicationInfo in AppStatusStore

### Why are the changes needed?
On invoking the method getSparkUser, we can get the SparkException on calling store.applicationInfo(). And this is not handled in the catch block and getSparkUser will error out in this scenario

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Done the manual testing using the spark-shell and spark-submit
