Fix client connect: expected Node response

[jonas089]

The node actually returns:

{"id":"cd8d0441","url":"wss://node.spectre-network.org/"}

not:

{"uid":"cd8d0441","url":"wss://node.spectre-network.org/"}

Therefore I chose to change the expected identifier in the wallet client to match the response data.

I tested it and it works @x100111010. You might wanna verify & merge.

Here is proof that it works (and my wallet ;)

@jonas089 Let me review it a bit later. With the merge of upstream changes into 0.3.16 we've also merged inscription related changes which require v2 resolver infrastructure. Anyway the change is much appreciated!
