Antigen tries to install plugins to root when logged in to root first

[lrustand]

Description

When I log in to the root user (with zsh and antigen) and then su to my user antigen tries to install all my plugins to /root. If I su to my user from bash or log in to that user directly it correctly finds my .antigen folder and all the installed plugins.

Steps to reproduce

Minimal steps to reproduce this behavior. Example:

1 - Log in as root (with zsh shell and antigen loaded)
2 - Su to a different user which also uses zsh and antigen
3 - Antigen tries to install the user's plugins to /root

Expected behavior:

- Everything works correctly
