Make `AutoMoveOneLineHandler::Run` explicitly ignore caret position when the destination is removed
The test case removes entire the `<output>` during deleting its content and
that occurs during it moves the content in `<div>` into the preceding `<ruby>`.
Therefore, the destination becomes not connected to the document so that it
fails to track the range of moved contents in the document.
Then, the code does not explicitly mark the caret position is not necessary.
So, we just need to do it.
