lazy-helm/helm-mini fails after permission changes of parent directory of a file

[tomichec]

Description

The problems appears when I try to switch the buffer which is usually done through the helm-mini (SPC b b).

I have been accessing some files before, but then changed the permissions of the directory where they are located, so my regular user does not have read rights any more.

Reproduction guide

1. make a new directory:
   mkdir -p /tmp/a/
2. save a new file into the directory:
   emacs /tmp/a/newfile
3. save, kill the buffer and change the permission (or ownership) of the directory
   chmod 000 /tmp/a/
4. SPC b b which runs the command lazy-helm/helm-mini fails with the following error
   helm-highlight-files: Getting attributes: Permission denied, /tmp/a/newfile

Observed behaviour:

The window with the frame helm-mini fails to open at such a situation, exiting with Permission denied error, regardless that I intend to visit another file than the one I have no longer access to.

Expected behaviour:

The inaccessible files are ignored (or marked as inaccessible), but the helm-mini still opens with what remains.
