Fix queueStore stops working with concurrent PUT/DELETE requests (#8381)

- This PR fixes situation to avoid underflow, this is possible
  because of disconnected operations in replay/sendEvents
- Hold right locks if Del() operation is performed in Get()
- Remove panic in the code and use loggerOnce
- Remove Timer and instead use Ticker instead for proper ticks
