    NIFI-4023, NIFI-4077: Addressed issue where repository was aging off …

    …the wrong index. When it should age off Index 1, it was removing Index 
2. As a result, the earliest index is never aged off, and the newest index 
could potentially be aged off before it is ready to be. Also addressed issue 
where a query that attempts to read an event that has aged off throws 
FileNotFoundException (NIFI-4077) instead of skipping over the event. The 
JavaDocs indicate that the EventIterator should skip records that it cannot 
find, but SelectiveRecordReaderEventIterator throw FileNotFoundException instead
