Generated project_root symlink slows down Intellij

See original GitHub issue

Background

With the recent changes to support buck-cells the following commit: https://github.com/facebook/buck/commit/8960005e2ec8900e8fc7c26a7b7239a7f512931a#diff-5ba521442393ce8db30deb6aa188a0eaR213 introduced a changeset that generates a symlink under buck-out/project_root that points back to the main project when running any sort of buck build command.

Issue

This introduces a potential infinite recursion in Intellij as the Git plugin attempts to resolve all the git roots and ultimately drills deep down into the symlink infinitely which causes performance issues in Intellij.
