Custom git.pushRepo test fails when upstream is set

[SuaYoo]

Minor dev issue: the 'should release to git.pushRepo' unit test fails in my fork. Looks like getting or reading the actual upstream URL isn't being stubbed.

To replicate locally:

1. Set upstream URL to anything: git remote add upstream git@github.com:SuaYoot/test-upstream.git
2. Run tests: npm test. Observe test fails with something like:

  github › should release to git.pushRepo

  Rejected promise returned by test. Reason:

  Error {
    message: `500 (request to https://api.github.com/repos/SuaYoo/test-upstream/releases failed, reason: Nock: No match for request {␊

    })`,
  }

  › })
  › GitHub.handleError (lib/plugin/github/GitHub.js:123:25)
  › retry (lib/plugin/github/GitHub.js:222:21)

3. Remove upstream: git remote remove upstream
4. Run tests again. Observe that tests now pass
