title: Owner can't push to organization repository
body: <p>today I've moved my private github repository to newly created organization (of which I'm an owner). I've changed my remote origin to git@github.com:organization/repo.git. I'm not able to push to remote because I've got an error saying</p>
  <blockquote>
  <p>Error: Permission to organization/repo.git denied to MyGithubUsername.</p>
  <p>fatal: Could not read from remote repository.</p>
  <p>Please make sure you have the correct access rights and the repository exists.</p>
  </blockquote>
  <p>I've checked that my account is owner of organization and repository exists.</p>
