[FIX] web_editor: avoid dialog error on email edition

Under certain unknown conditions, the range cannot be applied and
triggered an error. In order to allow the user to keep editing, we need
to prevent the dialog from showing, hence the use of `console.error`.
If this error appears, the carret is moved to the beginning of the focused
node.
If this error appears, then bullet can generate an error (I managed to
have the bug once or simulate it by manually breaking the dom and range)
