DATAREDIS-166 - Corrupted i/o streams subscribing to both patterns and channels.

The issue has already been fixed in [DATAREDIS-242](https://jira.springsource.org/browse/DATAREDIS-242) (see PR: #25), which now allows to reenable the previously failing test.
Additionally the tests now run against all supported client libraries except `JRedis` which does not support `publish`.
