Yarn: Error releasing v1.1.0

[DanBuild]

An error was encountered while processing the CircleCI release build of v1.1.0:

Build #5328 in wrong status (failed), expected "success". Not releasing it.

Re-running the build on CircleCI might fix it. Click "Rebuild" on this page to trigger a rebuild

Full logs: https://release.yarnpkg.com/log/release_circleci

@BYK Seems like this time it "failed" because publishing to npm failed (and we decided to do the npm publish as part of the CircleCI build a while back). Perhaps npm publish failing should not fail the build?

Hmm... is this some sort of NPM bug? o_O

++ npm publish ./artifacts/yarn-v1.1.0.tar.gz --access public --tag rc
npm ERR! Cannot read property 'algorithm' of undefined

Definitely an NPM bug: https://github.com/npm/npm/issues/16723

I've committed https://github.com/yarnpkg/yarn/commit/ee5d4a153a3fe85145c45c0bb251ffffffcfe210 to fix this but now I need to force-push the 1.1.0 tag to this commit :(

Seems to be out safely now, but the changelog in the release tag is missing (seems it was generated based only on the commit adding the npm@4 workaround)

@Kovensky Will deal with changelogs separately.
