Include intermediate directories in projectile-find-dir (#1596)

projectile-project-dirs previously only returned directories that
directly contain files, missing intermediate directories that contain
only subdirectories (e.g. src/ when it only has src/ComponentA/).

Fix by walking each file path's ancestor directories up to the project
root, so all intermediate directories are included.
