Reviewed by Carlos Garcia Campos.

In one of the subtests, we start downloading a local file and then
immediately cancel it.

When the download completes fast, `WebKitDownloadClient::didFinish()`
method can be called twice. Firstly, because the download is actually
completed, and secondly, from `Download::cancel()`'s completion handler,
which we set in `webkit_download_cancel()'.

Since we set `m_download` to `nullptr`
in `WebKitDownloadClient::didFinish()`, the second call will crash.

The solution is to call `WebKitDownloadClient::legacyDidCancel()`
instead of `WebKitDownloadClient::didFinish()` from the download's
cancel completion handler.
