Refactoring editing/selection/13804.html

This test does not need pixel baselines (linux, mac, win) to just
check whether or not spelling marker appears on 'adf'.

According to bug 295722, the test started using asynchronous
spellchecking.

Since the test verifies spelling behaviour, it was moved
to editing/spelling directory.
Its name was changed to spelling-backward.html.
