ISPN-3229 L1 cache entries should not be passivated

* Only passivated owned entries
* Added test for L1 entries not being passivated

Yeah I debated about making it L1 specific, technically it is possible to get values in here that aren't owned by this node that isn't L1, but those are so far and between that making it named L1 seems fine.
