Sometimes `helm-source-projectile-buffers-list` incorrectly chooses the buffer to skip

[marshall-lee]

Expected behavior

helm-source-projectile-buffers-list returns all project buffers except the current.

Actual behavior

Sometimes helm-source-projectile-buffers-list returns the current buffer but skips some other buffer.

Steps to reproduce the problem

1. Switch to a buffer.
2. Once again switch to a buffer by executing helm-projectile-switch-to-buffer fast enough using a keyboard shortcut.
3. Current buffer is in the list but some other buffer (maybe the one I want to switch to) is missing!
4. Once again switch to a buffer and everything is correct — current buffer is removed.

Demo

• On 0:07 it shows a helm-projectile.el buffer that shouldn't be shown since we're already on helm-projectile.el.
• Then, on 0:10 it shows a correct buffer.
