Due to a wrong order of operations, after splitting an anchor (press
ENTER), the range was setting on the first anchor. Now it sets on the
second one (as the code - but not the tests - suggests was supposed to
happen). Tests were adapted to reflect that change.
In tests, after splitting the anchor, `Wysiwyg.getValue` didn't always
properly clean up `data-original-title`. Targetting empty
`data-original-title` attribute instead of `aria-describedby` attribute
should fix that issue.
