Close only used HazelcastInstance

* It might be dangerous to shutdownAll() HazelcastInstances from the
test-case, especially when we are ran in with the integration test and on
the CI environment.
Therefore extract the instance variable in the test and close only it from
the @AfterClass
* Fix typo in the AbstractHazelcastRepositoryITests test method name
* Increase lock wait timeout to the 10 seconds in the SessionEventRegistry.
Looks like 3 seconds isn't enough for my Windows machine.

Fixes gh-358 gh-360
