Re: [presentation-api-tests] [presentation-api] Add a test case to check "change" event on PresentationAvailability (#4192)

@tidoust Thanks for reviewing and merging! By the way, I would like to ask one question:

> The test does not check that the initial availability value is true

I wonder whether the initial availability value is always `true` or not, when any presentation display has been available. I am afraid that there might be possibility a browser might start monitoring when `getAvailability()` would be invoked, fire a `change` event with the value `false` due to timeout for example, then soon find a presentation display and fire a `change` event with the value `true`. WDYT?
