title: Firebase verify email issue when using sendEmailVerification method in AngularFire2
body: <p><strong>Tech Stack:</strong></p>
  
  <p>Currently using angular6, firebase, angularfire2 and angularcli6.</p>
  
  <p><strong>Attempt / Issue:</strong> </p>
  
  <p>Currently on signup I call Firebase sendEmailVerification.</p>
  
  <p>This sends the user an email to verify their account.</p>
  
  <p>They click the link and it send the user to account-management page on my website.</p>
  
  <p>I then need to update the field emailVerified to true but it wont let me since its a readonly field.</p>
  
  <blockquote>
    <p>How can I update the currentUser with emailVerified set to true, as Firebase doesn't seem to do it automatically for me?</p>
