PutMapCommand fires CacheEntryModifiedEvent when creating new entry

PutMapCommand.perform calls notifier.notifyCacheEntryModified(...) for all entries. CacheNotifierTest.initCacheData(...) even expect this behaviour. PutKeyValueCommand.perform (correctly) checks that entry.isCreated() and in this case does not fire the event.

Generally, the place where the events are fired is quite inconsistent, since modifications are fired from perform() while creations from EntryFactoryImpl.
