Description

NIFI-1484 add few lines of code to avoid files to be emitted if those have the latest timestamp within an iteration of listing, because it may still be written at the same time.

While it doesn't affect much if ListFiles processor is scheduled with a short period of time, such as few ms, but it does affect negatively if an user scheduled it with longer run schedule such as "1 day" or with cron scheduler.

For example, user would expect to process list of files per daily basis. Even if a file is saved few hours ago, the processor will skip this, because the file has the latest timestamp within the iteration.
