The PluginManager incorrectly used synchronization on firing any event that was marked as synchronous. This synchronized did not even protect any concurrency risk as handlers were already thread safe in terms of mutations during event dispatch. The way it was used, has commonly led to deadlocks on the server, which results in a hard crash. This change removes the synchronize and adds some protection around enable/disable
