Bug 1834049: Permit canvas captureStream without initializing the context. r=lsalzman 

The spec does not seem to require a current context, so there's no reason
to require it here. If later calls within
`HTMLCanvasElement::CaptureStream` need a current context, they'll have
their own failure messages which will hopefully clarify where exactly we
need the context to exist.
