resp body needs to be closed at all times

[javorszky]

In the httpsource code, the response body is only closed when the dest, one of the input parameters, is not nil, but the request that produces the response body gets called either way.

That can lead to situations where the request is sent, there's a response, but the body is not closed, leading to possible memory leaks.

Code is here: https://github.com/suborbital/atmo/blob/main/atmo/appsource/httpsource.go#L275-L276
