Revert of Bailing out if pc factory fails to get created. (patchset #1 id:1 of https://codereview.webrtc.org/1339923004/ )

Reason for revert:
Breaks goma (??!??!?)

Original issue's description:
> Bailing out if pc factory fails to get created.
>
> This prevents us from continuing if we fail initialization.
> The failure will happen closer to its source, rather than
> when we try to create the first peer connection.
