SharedWorker refactor (#471)

refactor(shared-worker): reorganize `SharedWorker` code

Decouple and re-organize `SharedWorker` code for better maintainability.

perf(shared-worker): improved subscription state refresh logic

Additional query parameter (removed before sending) is added for requests triggered by user and
state will be updated only for these requests.

refactor(logger): avoid similar timestamp in sequential lines

Log entry timestamp will be altered on millisecond if multiple log entries have similar
timestamp (logged in fraction of nanoseconds).

refactor(shared-worker): change condition for stalled `ping` timer

Change the condition that is used to identify whether the `offline` detection timer has been
suspended by the browser or not before trying to evict "offline" PubNub clients.
