title: git push not working on a bitbucket repository
body: <p>I've just created a repository on my Bitbucket account. I have a code already written in my laptop.
  Here's the command I executed on my terminal:</p>
  <pre><code>git init
  git add --all
  git commit -m 'Initial commit'
  git remote add origin https://&lt;repo_owner_name&gt;@bitbucket.org/&lt;teamname&gt;/&lt;reponame&gt;.git
  git push origin master
  
  </code></pre>
  <p>I got the following error:</p>
  <pre><code> ! [rejected]        master -&gt; master (non-fast-forward)
  error: failed to push some refs to 'https://bitbucket.org/EtienneVergne/disney-app-proposal.git'
  hint: Updates were rejected because the tip of your current branch is behind
  hint: its remote counterpart. Integrate the remote changes (e.g.
  hint: 'git pull ...') before pushing again.
  
  </code></pre>
  <p>I've tried several git pull as suggested in the message with no sucess.</p>
  <p>Can somebody help me ?</p>
