Fix a bug when processing Flow Entry notifications and updating the
locally stored FlowEntries. Previously, even if a Flow Entry
wasn't updated, it could trigger multiple writing of a FlowPath
to the Database. Now we explicitly check whether the
locally stored FlowEntry is actually updated.

As a side-effect of the above fix now we have to:
(1) Create a copy of a FlowEntry inside FlowManager.flowEntriesPushedToSwitch()
before modifying it and pushing it into the Datagrid
(2) We have to explicitly check whether all Flow Entries have been installed
into the switches before writing a FlowPath to the Graph DB.
