    [SPARK-25900][WEBUI]If the When the page number is more than the total page 
size, then fall back to the first page

    ## What changes were proposed in this pull request?
    
    When we enter the page number more than the page size, webui is throwing an 
exception. It would be better if fall back to the default page, instead of 
throwing the exception in the web ui.
