.dir-locals.el variables are ignored

[dvzubarev]

I should use .dir-locals.el file for storing local project settings, according to doc. These settings do not work with helm-projectile.

Steps to reproduce the problem

1. Create temp project: mkdir /tmp/tmp_proj && cd /tmp/tmp_proj && touch .projectile MyBinaryFile echo '((nil . ((projectile-globally-ignored-files . ("MyBinaryFile")))))' > .dir-locals.el
2. Then open /tmp/tmp_proj/.projectile in emacs
3. M-x helm-projectile-find-file

Expected behavior

There is no MyBinaryFile in candidates.

Actual behavior

MyBinaryFile is on the candidates list. projectile-find-file works as expected. I printed some information within projectile-current-project-files function and noticed that the current buffer has changed in commit. At commit: (current-buffer) - .projectile (problem is not reproducible), at commit: (current-buffer) - *helm projectile* (problem is reproducible).

Environment & version information

• helm-projectile version: 20170613.1014
• helm version (in helm-pkg.el): 20170909.613, helm-core "2.8.4"
• projectile version (M-x projectile-version): 20170416.148
• Emacs version (M-x emacs-version): 25.2.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.22.11)
• OS: Ubuntu 17.04

The problem is that, when supplying a closure to :candidates in helm-build-sync-source, the closure doesn't get the dir-local value.

I'll have to discuss how best to resolve this w/ @thierryvolpiatto.
