Show a separator only when clicking a misspelling word.

This is another stupid mistake of mine while moving spellchecker-related context-menu to the SpellingMenuObserver class. (As written in r111881 <http://crrev.com/111881>, the original code shows this separator only when |misspelled_word| is not empty.) This change shows this separator only when this |misspelled_word| is not empty.
