title: When using Stripe Connect, how to handle 'account with this email already exists' errors?
body: <p>While working on an app that connects with Stripe Accounts, I ran into an issue.  If an account already exists for a given email, I can't create a new one.  Stripe throws an error.</p>
  
  <p>But how do I connect to that existing account?  I can't find anything anywhere to do so.</p>
  
  <p>For clarity, the failing code is:</p>
  
  <pre><code>Stripe::Acount.create(managed: false, email: 'Foo@UserEmail.address')
  </code></pre>
  
  <p>I'm creating a <code>Stripe::Account</code> object, not a <code>Stripe::Customer</code> object.  The above code throws an exception if the email already exists on Stripe's API, but does not provide me with any information to connect with it.</p>
  
  <p>My concern is if a user who already has a Stripe account attempts to join the site, how do I link them up.</p>
