Draft: Quickfix extra quotes by removing them from LSP response

[nick-loginov]

Fixes #885

[DaelonSuzuka]

I WAS going to tell you I've tried this by rewriting the incoming messages and it was so unreliable that I'm not interested in a client side bandaid fix anymore, but I've never seen this middleware mechanism.

I'm very interested to test this out.

[nick-loginov]

Yeah, I'm still testing it right now, and you're right, it's all junky and there is more stuff to make it work as intended. In current state only works for simple cases.

[DaelonSuzuka]

No problem. We can also slap a setting in front of this and mark it experimental.

I have some other dirty hacks that I think would be cleaner if I move them to this middleware layer, so this PR won't be wasted even if the quote thing doesn't work out.

@DaelonSuzuka I was going to ask what exactly was the problem in your attempts? Did some of the cases not work? Can you give some examples? I'm convinced it's possible to make it reliable
