When using the :LeaderBuffer command to open the buffer list, pressing ''' or ' 'to scroll to a buffer file that has been deleted causes an error to occur.

Steps to reproduce

1. vim open 5 files，don’t close vim
2. :e xx, and Edit multiple lines and stop in the middle,  :w
3. :bp, :bp, :bp, :bp
4. rm xx, from system
5. :LeaderBuffer
6. '<Down>' to xx
7. show error or '<Enter>' show error
