Some code in NetworkBlobRegistry assumes that a connection handler is already registered when executing unregisterBlob(). Normally this is is indeed the case, as WebProcess won't try to unregister a blob that it didn't register. But if we previously lost the whole registry due to an unrelated NetworkProcess crash, then this invariant doesn't hold. In fact, we already have some of these functions check for connection, but not all. <rdar://problem/16951630>
