enha: send original error response in ProxyGetRequest

[dcfreire]

closes #1515

[dcfreire]

I tried using an enum instead of deserializing in two places, but it did not work, serde kept failing with "data did not match any variant of untagged enum". I think it has something to do with untagged enums expecting all parameters of the json object to be in the variant's struct, while structs will deserialize even if the json contains extra fields.

Yes, we are using serde_json::value::RawValue which doesn't work with untagged enums serde-rs/json#779

If you merge master then the UI tests should pass I fixed it right now, new stable rust version broke it

Suggested change

	error: &'a serde_json::value::RawValue,
	error: ErrorObject<'a>,

I applied this by mistake, if it is ok here to directly deserialize to the error object, why not also directly deserialize the result in the success response?

Also I think in this case we can just do serde_json::from_slice::<ErrorObject>(&bytes) and not have the ErrorResponse struct at all

This is incorrect, my bad
