Queues that use in memory storage cannot run reclaim on abandonded localstorage queues

[Dahaden]

Something we have started to see recently in an extreme case, is when the localstorage is full of events from abandoned queues, localstorage-retry is unable to reclaim these queues.

In theory, queues should be able to be cleaned up as they move to localstorage, but in some extreme cases, we are seeing the clean up halt half way through and all new queues resort to in memory store.

Currently, this leaves localstorage-retry in an unrecoverable state, where is will always use in memory storage over local storage.

To fix this, we should be able to run the reclaim mechanism on localstorage, even when the main queue is in memory.
