Bug 1445009: Refactor BrowserErrorReporter.jsm and tests. r=Gijs The transforms for turning an nsIScriptError into a payload that Sentry understands were getting a bit complex for a single function, so they're refactored into a list of transform functions that are applied in sequence to produce the payload. This will make it easier to manage adding new transforms to the list. Refactoring this revaled a problem with the test code: it assumed that listeners for console messages were notified in order of registration (since it used a temporary listener to determine when the rest of the listeners had been notified of a message). Changing the async evaluation of the code broke the tests, so they had to be refactored as well. Without a way to know when all console listeners have been notified, we can't assert that a message will not be received by BrowserErrorReporter. We do two things to get around this: - Where possible, call `observe` directly on the reporter instance. - Add constructor params for registering and unregistering listeners so we can test that logic without relying on messages being received or not.

Bug 1444489 - Part VII, Transition the visibility property instead of using transitionend event Fades out all the UIs by applying CSS transition on opacity and visibility.
