What: Fixes the ByRole methods to accept filter hidden elements using name and description. Also fixes the logs to show the accessible name in case of not found error. Related to #846

Why: If we have two hidden elements with the same role we can't filter that using the name. Also when we have hidden elements on logs they don't have the name filled, they are always equal ""

How: By adding the hidden option when use computeAccessibleDescription and computeAccessibleName to get the accessible description and name

Let's keep this test. I don't think it's relevant to the change. If there is something important here, lets's add a new test instead so that we can better track what changed

The idea was to test the case where an element had a name available to be filtered but is hidden, before that change the name was always empty. May we can add a test specifically for that case? What do you think?

Always add test instead of re-purposing existing tests. Existing tests should only change their assertions if they relied on buggy behavior.

Thank you! I'm learning about all that tests concepts and patterns.

The problem is that the accessible name is different if the element is hidden. See #846 (comment)

So this adds a footgun where you just flip hidden and expect name to return the same set. I wasn't convinced by #846 fully to implement this so let's add some concrete, high level use cases to #846 first (e.g. what are you testing?).
