Reporter: Move HTML related files to a new JS file
Core: Removal of QUnit.init

It's now properly called through QUnit callback

Reporter: Moving html reports for test init and finish logs
Reporter: Stop passing test as reference in log callbacks

It should be further implemented on the HTML reporter
Reporter: Get nameHtml from testDone details

They were trying to test assertions being assigned to it's
own current tests instead of leaking to other tests.

Although they proved their bad implementation on #583 and
they should be implemented on logging tests.

Also they're testing the HTML Reporter only.
Reporter: Set the Running Test status on HTML reporter
Core: Remove unused nameHtml property from Test
Reporter: Implements assert logging in HTML
