Stubbing doesn't work with Hash#fetch

[sindrenm]

Soeh, it looks like Hash#fetch doesn't really call [] at all.

it "gets 'pokémanz' from WHATMON, not 'digimon'" do
  ENV["WHATMON"] = "digimon"
  stub_env "WHATMON", "pokémanz"
  expect(ENV.fetch("WHATMON")).to eq "pokémanz"
end

The result:

Failure/Error: expect(ENV.fetch("WHATMON")).to eq "pokémanz"

  expected: "pokémanz"
       got: "digimon"

  (compared using ==)

However, this passes as expected (notice I've changed fetch into [] syntax:

it "gets 'pokémanz' from WHATMON, not 'digimon'" do
  ENV["WHATMON"] = "digimon"
  stub_env "WHATMON", "pokémanz"
  expect(ENV["WHATMON"]).to eq "pokémanz"
end
