title: why helm-projectile-recentf set current buffer as default
body: <p>I'm trying move from ido-mode to <code>helm</code> and <code>projectile</code> and are not used to, something will be overcome, but when I tried <code>helm-projectile-recentf</code>, I wish it can switch to last buffer I visited quickly, but the default buffer is my current buffer, I don't want to switch to my current buffer, I have to move down first. switch buffer is a very frequent operation, I think move down everytime is very annoying!</p>
  
  <p>I have studied <code>helm-projectile-recentf</code> function, it seems it is not easy to customize it to suit my normal requirement. </p>
  
  <p>Could somebody have good suggestion, thanks in advance!</p>
