Log Message:
-----------
Occasional crash in `WebViewImpl::setMarkedText` (`com.apple.WebKit:
_ZN6WebKit11WebViewImpl13setMarkedTextEP11objc_object8_NSRangeS3_`)

Reviewed by Abrar Rahman Protyasha.
The existing logic to ensure that `setWritingSuggestions` only gets called when
`string` is an
`NSAttributedString` was flawed in some cases (when
`m_isHandlingAcceptedCandidate == true` and `hasTextCompletion == false`).
This resulted in `-[NSAttributedString string]` being called on an `NSString`,
causing a crash.
