after delete file, leaderf will still search and hit the file . for example， the first file was deleted，but still appear at top of the result.

### Steps to reproduce

### Actual behaviour

### Expected behaviour

[Yggdroot]

Because current command using is git ls-files "." && git ls-files --others --exclude-standard ".", if you delete a file from a git repository, you should use git rm.

Anyway, you can set let g:Lf_UseVersionControlTool = 0 to bypass the issue.
