Crash in `DownloadProxyMap::downloadFinished` during network process teardown

Reviewed by Chris Dumez.
If `NetworkProcessProxy` begins destruction while the `CancelDownload` message
is in flight all downloads
will have already been cleared. Calling `DownloadProxyMap::downloadFinished`
with the `DownloadProxy`
being kept alive in the lambda capture will dereference a null
`NetworkProcessProxy`.
