RSpec/Rails/HttpStatus works partially with last_response

[ericproulx]

last_response addition doesn't work with the have_http_status matcher since it's a Rails/Matcher that acts on ActionDispatch::TestResponse

Although, I think enforcing the style be_status should describe an offense like

RSpecRails/HaveHttpStatus: Prefer expect(last_response).to be_successful over expect(last_response.status).to eq(200)

instead of

RSpecRails/HaveHttpStatus: Prefer expect(last_response).to have_http_status(200) over expect(last_response.status).to eq(200).

I don't know if there's a way to implicitely enforce be_*** style when last_reponse is found. I'm not that familiar with AST.
Maybe it could be its own cop but outside of Rails.
