Ok so with 100 milliseconds I have seen the test fail when run with a large 
number of iterations due to loss connection to the local ZooKeeperTestServer 
when the server's up.
I haven't found the root cause but 100 milliseconds is way lower than usually 
zookeeper setup and it may mess with zookeeper's tickTime. And the way we're 
using the test server is a bit hacky anyway.
I think the wait for ZooKeeperTestServer to expire the session is not an 
essential part of the detector test so I removed it and split the test into two.
