[SPARK-25683][CORE] Updated the log for the firstTime event Drop occurs
## What changes were proposed in this pull request?
When the first dropEvent occurs, LastReportTimestamp was printing in the
log as Wed Dec 31 16:00:00 PST 1969
(Dropped 1 events from eventLog since Wed Dec 31 16:00:00 PST 1969.)
The reason is that lastReportTimestamp initialized with 0.
Now log is updated to print "... since the application starts" if
'lastReportTimestamp' == 0. this will happens first dropEvent occurs.
## How was this patch tested? Manually verified.
Closes #22677 from shivusondur/AsyncEvent1.
