eventsByTags() and currentEventsByTags() not working correct in latest version 0.16

Hi, i think there are two bugs in the persistence query part which are not covered by the test cases.

eventsByTags() not working - the subscription part is failing. In the first run everything works fine but the streams freezes and waits for new messages.

And the offset of is not working. I think the comparision of Long and Option Long while filtering is the problem. It always starts from scratch.
currentEventsByTags()
