Fixes #1430
Many users are reporting that nbconvert 6.x has permission errors when queried or converting files. These seem to arise when nbconvert is installed as root, then used as a user. We hypothesize that the code removed in this commit, which attempts to create template directories throughout the jupyter path hierarchy, succeeds in creating template directories when running as root. Note that it creates the template directories with permission 700. Those permissions as root mean that regular users won’t be able to read these directories, and those are the sort of permission errors we are seeing reported.
This directory creation was originally introduced in #1028, where I think it was limited to a single user configuration directory (based on the PR discussion). In #1056, this code appears to have been copied over and applied to the entire Jupyter directory hierarchy.
