The original goal here is to remove the warning of the google page
speed but it actually is really better to use 'pagehide' as it is fired
more reliably than the 'unload' event and does not prevent Chrome and
Firefox to use the bfcache (browser optimization that enables instant
back and forward navigation).
The persisted property of the pagehide event is checked before
disconnecting from the worker. As for the presence/multi_tab case, it
was chosen to also consider page freezing as it seems more accurate that
what was done before (the main tab could be throttled/frozen which was
an issue).
Some resources to explain why this is better:

When a tab is closed (unloads), the main tab is still considered the main tab
and event listeners are not properly removed.
In practice, it's probably not an issue because the tab is killed by the browser,
but it could still potentially have unexpected and undesired side effects.
It's safer to clean everything properly.
The issue is much more visible in tests because the mutli_tab and bus services
are still "active" after we simulated a tab unload.
