dumpAsText() is unnecessarily called in spellchecking tests

dumpAsText() is unnecessarily called in spellchecking tests

dumpAsText is already called either by notifyDone (js-test-post.js) or
by finishJSTest() when asynchronous spell checking is used.

This is mostly WebKit changeset: http://trac.webkit.org/changeset/157949

In addition, remove dumpAsText and notifyDone from Blink's spellchecking
tests where they should not have been added.
