DirtySummaryEventListener will never refresh

[RafaelKr]

The DirtySummaryEventListener uses the RefreshAgentRunner to trigger a RefreshAgentStartCommand with a delay of 1 second.

After 1 second the RefreshAgentStartCommand will be handled by the RefreshAgent. It will trigger a call to SummaryRefresher->refresh() but without any arguments. This means the DefaultRefreshAgentStrategy with a minimumIdleDelay of 300 (5 minutes) will be used.

As 1 second < 300 seconds the command will never do an actual refresh. Does the RefreshAgent need to pass a RefreshAgentStrategy to the refresh method?

Please ignore the referenced commits. They made my message consumer hang up with high CPU load.

This is not true anymore with the fix to $latestKey caching in the SummaryHandler.

This is fixed by #656
