Fix issue which unsubscribed additional channels (#459)

fix(shared-worker): fix issue which unsubscribed additional channels

Fix issue that has been caused by the race of conditions on tab close and led to `presence leave`
for channels that were still in use.

refactor(shared-worker): change leeway for rapid heartbeat filter out

Make leeway depending from the minimal heartbeat interval (5% from it) to filter out too rapid
heartbeat calls.
