Charts of Statistics http/sql etc, can not be viewed after restarting the application

[goldyliang]

The charts under each http/sql request entry can be viewed normally. However if the application is restarted, the charts can not be seen anymore, unless there are several requests coming and 're-activate' the charts.

After some reading of the code, I have found the source of the issue and changed the code to make it work.

The problem is in Collector.getJRobin. After restarting, the http/sql graphs are not added into any of the JRobin collections so getJRobin return null even the RRD file really exists. My quick fix is to create a temporary JRobin object and return that if no JRobin object is found in the collections.

I will send a PR soon for this change.
