Fix a null pointer dereference in CreateProfileHandler::ShowProfileCreationError.

The ProfileManager can call its callback (which points to CreateProfileHandler::OnProfileCreated) with a NULL profile (https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/profiles/profile_manager.cc&l=397). This case was not handled in CreateProfileHandler::ShowProfileCreationError.
