querying for events with specified actors

[Seif Lotfy]

When querying for events with specified actors i get the following scenarios.
1) events for actors exists and i get the right events back (Which is ok)
2) actor does not exists so events shouldnt exist either, HOWEVER I get back some set of events that makes no sense to me
I couldnt produce it over test cases but i added a script that will demo it.

revno 1222 has a remote testcase for this bug, which fails.
A testcase which does the same on engine level works just fine.

My last comment is kind of wrong, I adjusted the engine testcase in my last commit to fail too

I think this is a case where "where.may_have_results()" in resonance_engine.py line 569 should return True (which results in find_eventids returning an empty list), but it does not work this way.
I think someone with a full understanding of the logic going on there should be able to provide a quick fix, Siegfried?

Fixed.

(This was a new regression, release 0.3.0 wasn't affected by it.)
