[O] org-attach-sync does not properly use ATTACH_DIR property

[Willy Rempel]

Hello all,

First time posting, let me know what I'm doing wrong.

Error:

cd: No such directory found via CDPATH environment variable

org-attach-sync calls org-attach-commit before evaluating attach-dir. 

org-attach-commit just uses the default '../data' in org-attach-directory.

So if I attach a directory with a different name, I get above error. 

Not sure what ATTACH_DIR is for if we should only attach folders called 'data'. The org manual is a little hazy.

Thanks
