Hickup in event stream feeder resets stream time

[kurzum]

https://github.com/dbpedia/extraction-framework/blob/live-deployed/live/src/main/java/org/dbpedia/extraction/live/feeder/EventStreamsFeeder.java

if AKKA stream fails, the initial time is used, not latestProcessDate, cascading in maxLine exceeded Illegal state exception.

There was an attempt to fix this, but it is unclear whether this works.

Fix was in this line: https://github.com/dbpedia/extraction-framework/blob/live-deployed/live/src/main/scala/org/dbpedia/extraction/live/feeder/EventStreamsHelper.scala#L101
