Reviewed by Chris Dumez.

When isolatedCopying() && a URLKeepingBlobAlive, we would register the blob URL handle for the new URLKeepingBlobAlive,
but the moved URLKeepingBlobAlive would no longer unregister itself if its url is empty.
To prevent this, we remove the isolatedCopy() && version.
We could make URLKeepingBlobAlive to a move only type in a follow-up.
